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

Description。This is the SparkFun RFM69 Breakout， a small piece of tech that breaks out all the pins available on the RFM69HCW module as well as making the transceiver easy to use. The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM(Industry， Science and Medicine)radio band. It's perfect for building inexpensive short-range wireless networks of sensors and actuators for home automation， citizen science and more.。This RFM69HCW operates on the 434MHz frequency and is capable of transmitting at up to 100mW and up to 300kbps， but you can change both of those values to fit your application. For example， you can maximize range by increasing the transmit power and reducing the data rate， or you can reduce both for short-range sensor networks that sip battery power. At full power and with simple wire antennas， we can get messages from one side of a large office building to the other through numerous internal walls. In open air you can reach 500 meters or more. With more complex antennas and modulation schemes， similar parts have successfully transmitted from space to the ground(by very smart amateur radio enthusiasts； your mileage may vary)!。The RFM69HCW uses an SPI(Serial Peripheral Interface)to communicate with a host microcontroller， and several good Arduino libraries are available. It supports up to 256 networks of 255 nodes per network， features AES encryption to keep your data private， and transmits data packets up to 66 bytes long.。SparkFun sells two versions of the RFM69HCW：a 915MHz version and this 434MHz version. Although the ISM band is license-free， the band itself is different in different areas. Very roughly， 915MHz is for use in the Americas， and the 434MHz version is for use in Europe， Asia and Africa. Check your local regulations for other areas.。Get Started with the RFM69HCW Hookup Guide。Features。Transmit power：-18dBm(0.016mW)to +20dBm(100mW)in 1dBm steps。Receive sensitivity：down to -120dBm at 1.2kbps。Modulation types：FSK GFSK MSK GMSK OOK。Bit rates(FSK)：1.2kbps to 300kbps。Voltage range：1.8V to 3.6V。Current consumption：0.1uA sleep， 1.25mA standby， 16mA receive， 130mA transmit(max)。Encryption：AES 128-bit(optional)。Packet buffer(FIFO)：66 bytes。0.8"×1.1"

Description。The Raspberry Pi Compute Module 3+ Lite contains the guts of a Raspberry Pi 3 Model B+(the BCM2837 processor and 1GB LPDDR2 RAM). This module allows a designer to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors. In addition this module has extra IO interfaces over and above what is available on the Raspberry Pi model A/B boards， opening up more options for the designer.。This is all integrated onto a small(67.6mm×31mm)board that fits into a standard DDR2 SODIMM connector. You get the full flexibility of the BCM2837 SoC(which means that many more GPIOs and interfaces are available than with a standard Raspberry Pi)， and designing the Module into a custom system should be relatively straightforward because all the tricky bits have been put onto the Module itself.。The CM3+ Lite product is the same as CM3+ except the eMMC Flash is not fitted， and the SD/eMMC interface pins are available for the user to connect their own SD/eMMC device. Note that the CM3+ is electrically identical and， with the exception of higher CPU z-height， physically identical to the legacy CM3 products.。Note：The CM3+ modules require a software/firmware image dated November 2018 or newer to function correctly.。Features。Broadcom BCM2837B0， Cortex-A53(ARMv8)64-bit SoC @ 1.2GHz。1GB LPDDR2 SDRAM。Operating Supply Voltage：1.8V， 3.3V。Minimum Operating Temperature：-25C。Maximum Operating Temperature：+80C。HDMI， MIPI， USB， and GPIO interfaces on edge connector

Description。The SparkFun RTK Surveyor is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying， this preprogrammed device can also be used for autonomous driving， navigation， asset tracking and any other application where there is a clear view of the sky. The RTK Surveyor can also be used as a base station. With the flick of a switch， two RTK Surveyors can be used to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth(R)connection via an ESP32 WROOM enables the user to use the RTK Surveyor with their choice of GIS application on a phone or tablet. The built in battery allows field use for up to four hours and is compatible with common USB battery banks.。This device can be used in four modes：GNSS Positioning(～30cm accuracy)。GNSS Positioning with RTK(1.4cm accuracy)。GNSS Base Station。GNSS Base Station NTRIP Server。In Position mode the device receives L1/L2 signals from a user-provided antenna and the high-grade GNSS receiver provides lat/long and altitude with accuracies around 300mm.。In Positioning with RTK mode the device receives L1/L2 signals from the antenna and correction data from a base station. The correction data can be obtained from a cellular link to online correction sources or over a radio link to a 2nd RTK Surveyor setup as a base station.。In Base Station mode the device is mounted to a temporary position(like a tripod)and begins transmitting correction data over a radio or internet connection. A base is often used in conjunction with a second unit set to 'Positioning with RTK' to obtain the 14mm relative accuracy.。In Base Station NTRIP Server mode the device is mounted to a semi or permanently fixed position(like a roof)and connects over WiFi to transmit the correction data to a NTRIP caster so that any rover can access the correction data over a cellular or internet connection. This type of base is a very easy way to setup a very precise absolute correction source.。Two cables are provided with the RTK Surveyor allowing a user to plug on our easy to use Serial Telemetry Radios or their own radio link. If a local correction source is within 10km， a user can also use their phone to provide correction data over the Bluetooth(R)link(no external radio needed!).。Note：The SparkFun RTK Surveyor is just the enclosed device and does NOT include an antenna， serial telemetry radio， or associated mounting pieces.
