14ビット分解能で冷接点補償を備えた熱電対-デジタルコンバータ K型熱電対と組み合わせて使用するGroveシステムの熱電対デジタル変換器です。サーミスタより広い測定範囲を持ちます。採用しているMAX31850Kには、アンプ、A/Dコンバータ、64ビットROMが搭載され、各デバイスに独自の64ビットシリアルコードを割り振ることで、複数のユニットを1-Wireバスで機能させることができます。したがって、1台のコントローラで多数の熱電対を使った温度監視が可能になります。 ・温度変換範囲：-270℃～+1768℃の測定が可能 ・分解能：14ビット、0.25℃ ・冷接点補償機能を内蔵 ・熱電対の開放を検出 ・GNDまたはVDDへの短絡を検出

Sometimes LED feedback isn't enough、like when you're flying around in a lab or a living room. With the buzzer deck you'll get audio feedback on system events、like low battery or charging completed. Or why not create your own melodies that will play while you're buzzing around. To get started using the buzzer deck there's already a few melodies pre-programmed in the Crazyflie 2.0 latest firmware.。This product is intended to be used together with the Crazyflie 2.0 nano quadcopter and uses its expansion board system. Please have a look at the buyers guide for more info about the Crazyflie 2.0 ecosystem. For more information about how to use the expansion decks check out the getting started with expansion decks page.。Features：Low profile piezo buzzer for tone and melody generation。Automatic detection of deck。Specifications。Based on the CMT-1203-SMT。1-wire memory for automatic deck detection。Mechanical specification。Weight：1.8g。Size(WxHxD)：25x27x4mm。Designed for mounting above or under the Crazyflie 2.0。Part list。1×Buzzer deck

With the BigQuad deck you can transform your Crazyflie 2.0 to a bigger quad by connecting external ESCs(Electronic Speed Controller)to the breakout connectors on the deck. The autodetection of the deck makes this transformation possible to do in seconds. The deck contains breakout header connectors for additional accessories such as external receiver(CPPM input)and GPS. It also has the possibility to monitor battery voltage and current.。This product is intended to be used together with the Crazyflie 2.0 quadcopter and uses its expansion board system. Please have a look at the buyers guide for more info about the Crazyflie 2.0 ecosystem. For more information about how to use the expansion decks check out the getting started with expansion decks page.。Early Access：This product is currently part of the early access program. This means the hardware is ready and low level tested but the firmware/software is still in a very rudimentary state、there are probably basic drivers for communicating with the hardware、but no higher level functionality.。Features：4×ESC connectors。0.1"header mounting holes for additional connectivity：CPPM input(3 pin)。GPS input(4 pin)。I2C expansion(4 pin)。Battery and current monitoring input(3 pin)。Buzzer output(2 pin)。Connect one or two additional decks。Automatic detection of expansion deck。Electrical specification：Power Crazyflie 2.0 with 4.5V - 5.5V from ESC.。BiqQuad deck inputs are 5V tolerant.。Battery voltage monitoring divider scaled for input up to 23V.。Current monitoring input 0V - 3V.。BiqQuad deck and Crazyflie 2.0 current consumption：～120mA without any additional decks.。Up to 500mA if Crazyflie 2.0 battery is connected and charging.。1-wire memory for automatic expansion deck detection.。Mechanical specification：Weight：3.8g。Size(WxHxD)：36x40x5mm。M3 mounting holes placed 30.5mm square.。Designed for mounting above or under the Crazyflie 2.0。Package contents：1×BigQuad deck。4×M2x4 nylon screw。2×M2x6 hex spacer
