WdKA RIoT Arduino Shield

WdKA RIoT Arduino Shield

The WDKA Riot Shield is a simple Arduino shield with a Microchip RN2483 LoRa transceiver module. The shield has the following inputs:

• 2 analog resistance based sensors like RTDs (PTC/NTC) or LDRs. The resistive sensors form a voltage divider together with a 10kΩ ground.
• 1 electret microphone input using the MAX4466 as amplifier module.
• 1 LittleBit input. The LittleBit chain needs to be separately powered through a LittleBit power module at the beginning of the chain.
