Description。This is the PICkit 4， the official programmer from Microchip. The PICkit 4 allows debugging and programming of PIC(R)， dsPIC(R)， AVR， SAM and CEC flash microcontrollers and MPUs using the powerful graphical user interface of the MPLAB X Integrated Development Environment(IDE). The MPLAB PICkit 4 is connected to a PC using a high-speed 2.0 USB interface and can be connected to the target via an 8-pin Single In-Line(SIL)connector. The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming(TM)(ICSP(TM)). An additional micro SD card slot and the ability to be self-powered from the target means you can take your code with you and program on the go. Comes with a USB to micro-B USB cable.。Features。Powered by a high-speed USB 2.0， no external power required。Real-time execution。MPLAB X IDE compatible(free copy included)。Built-in over-voltage/short circuit monitor。Firmware upgradeable from PC/web download。Fully enclosed。Target voltage of 1.20V to 5.5V。Can supply up to 50mA of power to the target。Minimal current consumption at <100μA from target。Diagnostic LEDs(power， busy， error)。Read/write program and data memory of microcontroller。Erase of program memory space with verification。Freeze-peripherals at breakpoint。8-pin single in-line header supports advanced interfaces such as 4-wire JTAG and Serial Wire Debug with streaming Data Gateway。Backward compatible for demo boards， headers and target systems using 2-wire JTAG and ICSP

。Description。The SparkFun MicroMod Update Tool is built to interface with the MicroMod Asset Tracker Carrier Board and also makes it simple to communicate directly with the u-blox SARA-R510M8S module using u-blox's sophisticated m-center cellular evaluation software. If you're familiar with u-center， u-blox's GNSS evaluation software， you'll know how excellent their software is. m-center is every bit as good. Attach a USB-C cable and away you go!。The Update Tool is not a full MicroMod Processor Board， it is much simpler than that. It has a CH340C USB-Serial converter on it which gives you full access to all eight pins of the SARA-R5's UART interface via the Asset Tracker's USB-C connector. Think of it as a bridge from USB to serial.。The Update Tool features eight pairs of Plated Through Hole connections for the UART signals. You can use these to connect directly to the SARA UART using 3.3V signals if you want to. The split pads on the rear of the Tool can be opened to isolate the CH340C completely； the pins nearest the M.2 will link straight to the SARA UART.。Get Started with the MicroMod Update Tool Hookup Guide。Features。CH340C USB-Serial converter。Eight pairs of Plated Through Hole connections with split pad jumper links for：Serial Transmit(TX)。Serial Receive(RX)。Request To Send(RTS)。Clear To Send(CTS)。Data Terminal Ready(DTR)。Data Set Ready(DSR)。Ring Indicator(RI)。Data Carrier Detect(DCD)。LED indicator for：Power(3.3V)

Description。Your 5V system can wield great power with this big， beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts at 220VAC sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!。The heart of the board is sealed， SPDT 20A/10A Relay. The relay is controlled by 5V logic through transistor， and an LED tells you when the relay is closed. This is kit， so it comes as through-hole parts with assembly required， which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project.。There are some pretty beefy traces connecting the relay to the load pins， but the 3-pin terminals are only rated for 15A max! If you plan on connecting larger load， you'll need to solder directly to the board. As always with high current and voltage， play it safe and use your judgment when deciding how much of load you want to put on board -- in open airflow the PCB can handle the full 20A for few minutes at time， but in an enclosed area heat can build up.。Note：Please keep in mind that this board is really meant for someone with experience and good knowledge of electricity. If you're uncomfortable soldering or dealing with high voltage， please check out the IoT Power Relay. The IoT Power Relay is fully enclosed， making it lot safer.。Get Started With the Beefcake Hookup Assembly Guide。Features。Voltage Rating：220VAC/28VDC。VCC requirements：4-6V， 150mA capable。SPDT pins exposed(Form C)。14 AWG screw terminals for relay connections.。10 AWG solder lugs for relay connections.。Flyback diode included。Zener recovery diode included(decreases turn-off time)。Heavy oz. copper on PCB

Description。The SparkFun LTE CAT M1/NB-IoT Shield with Hologram SIM Card equips your Arduino or Arduino-compatible microcontroller with access to data networks across the globe without needing to provide your own subscriber identity module. This shield adds wireless， high-bandwidth cellular functionality to your IoT project while maintaining low power consumption and a small footprint. The SparkFun LTE CAT M1/NB-IoT Shield is based off the Arduino R3's footprint that allows you to easily incorporate it with favorite Arduino-based device.。At the heart of the LTE Cat M1/NB-IoT shield is a u-blox SARA-R410M-02B LTE Cat M1/NB-IoT modem. Cat M1(Category M1)and NB-IoT(Narrowband IoT)are both Low Power Wide Area Network(LPWAN)technologies that are designed to provide cellular communication to small IoT devices. They operate on LTE network bands just like most smartphones， and should be supported by most cellular network carriers. The u-blox SARA-R4 module communicates over a UART via a simple AT command set. We've provided a library to help you get started with everything from sending SMS text messages to communicating with servers over a TCP/IP connection. Additionally， both the module and library support an I2C GPS interface via a Qwiic connector， so you can plug in a u-blox GPS module and start remotely tracking your project.。Each SparkFun LTE CAT M1/NB-IoT Shield also includes a ceramic， Molex 1462000001 SMD antenna. The antenna has a gain of 3.8dBi around 1.7GHz to 2.7GHz. However， if you would prefer to use an external antenna， we have provided a U.FL connector that can be utilized by simply slicing through a jumper with a hobby knife.。Please be aware that you will need to supply and solder on your own headers before attaching it to your Arduino based device. Also， if you already have your own SIM， we also offer this shield without a card included.。Note：。Be sure to check the。Hardware Overview。section in the Hookup Guide for compatible GPS modules. The onboard Qwiic connector is only designed to support u-blox-based GPS modules. It does not support any other GPS modules or sensors. We are continuing to add more modules so be sure to check back every so often to find out more!。Get Started with the SparkFun LTE CAT M1/NB-IoT Shield Guide

Description。Are you low on I/O? No problem! The SX1509 Breakout is 16-channel GPIO expander with an I2C interface that means with just two wires， your microcontroller can interface with 16 fully configurable digital input/output pins. But the SX1509 can do so much more than just simple digital pin control. It can produce PWM signals， so you can dim LEDs. It can be set to blink or even breathe pins at varying rates. This breakout is similar to multiplexer or "mux，" in that it allows you to get more IO from less pins. And， with built-in keypad engine， it can interface with up to 64 buttons set up in an 8x8 matrix.。Two headers at the top and bottom of the breakout board function as the input and control headers to the board. This is where you can supply power to the SX1509， and where your I2C signals SDA and SCL will terminate. GPIO and power buses are broken out in every-which direction， and configurable jumpers cover most of the rest of the board.。Since the I/O banks can operate between 1.2V and 3.6V(5.5V tolerant)independent of both the core and each other， this device can also work as level-shifter. The SX1509 breakout makes it easy to prototype so you can add more I/O onto your Arduino or I/O limited controller. We've even spun up an Arduino Library to get you started!。Features。Enable Direct Level Shifting Between I/O Banks and Host Controller。5.5V Tolerant I/Os， Up to 15mA Output Sink on All I/Os。Integrated LED Driver with Intensity Control。On-Chip Keypad Scanning Engine Supports Up to 8x8 Matrix(64 Keys)。16 Channels of True Bi-directional Style I/O。400kHz I2C Compatible Slave Interface
