Description
**General**
Powered by 2 AA Batteries Size 20 x 45 (mm) Almost SMD 0805 Atmel328p TQFP32 NRF24I01 smd ATSHA204A chip FLASH for OTA FTDI, ISP SHT21 Sensor
**Description**
The Sensor works directly on two AA Batteries or Ni-MH.
**Settings**
Use Sensebender Micro bootloader Set Fuses before upload bootloader FUSES: L: 0XDE // H: 0XD2 // E: 0X07 (disabled BOD/8Mhz external clock) Set Fuses again, arduino IDE will override it with the default sensebender fuses or modify the board settings in Arduino IDE
