|
|
|
|
* Based on widely available Atmel ATTiny84 MCU and RFM95W LoRa-module
|
|
|
|
|
* 6 free GPIO-Pins from the ATTiny + Power to connect sensors on a 2.54mm pitch header
|
|
|
|
|
* Optional on-board LED for status signaling
|
|
|
|
|
* Powered by a single CR2032 lithium battery
|
|
|
|
|

|
|
|
|
|
* Integrated 6-Pin programming header
|
|
|
|
|
