JMP ArduinoProMini Multisensor Board
Arduino Pro Mini board for MySensors,the board is designed for multiple sensors.
Supply
- LiOn battery
- 5V
- 2xAA battery
Boards features:
- LiOn battery support
- NRF24L01+ support
- RFM69 support
- ATSHA204A signing chip
- AT25DF512C EEPROM chip
- designed for multiple sensors (multiple I2C sensors, analog and digital sensors)
- Accept Arduino Pro Mini 3.3V and 5V
LiOn Battery --> 3.3V - Arduino Pro Mini 8Mhz and 3.3V
- Weld the regulator (IC1) and the other capacitor (Cin,Cout, C-NRF, etc)
- short-circuit the 3.3v jumper
- weld the C1, R1, R2 parts (voltage divider circuit)
- use a TP4056 module and attach the LiOn battery on X1 input
5V - Arduino Pro Mini 16Mhz and 5V
- Weld the regulator (IC1) and the other capacitor (Cin,Cout, C-NRF, etc)
- short-circuit the 5v jumper and J2 pad
- attach the the 5V supply on X3 input
- the regulator gives 3.3v only to antenna
AA Battery --> 3V - Arduino Pro Mini 8Mhz and 3.3V
- DON'T weld the regulator (IC1)
- Weld the C-NRF capacitor
- short-circuit the 3.3v and 5V jumper, J2 pad
- weld the C1, R1, R2 parts (voltage divider circuit)
- attach the 2xAA battery on X3 input
Please note: the sensor images refer to previous version of the board
