CE and CSN pins of the NRF24 socket are connected to digital pins 7 and 8. There is a 10uF capacitor connected across Vin and GND of the socket. Bluetooth socket has RX and TX pins connected to digital pins D5 and D6.
The board comes with an MPC1703 3.3V as a standard, which has an amazingly low 2uA quiescent current and high, 16V maximum input voltage. It can be equipped with other kind upon request.
and 10k pull-up resistors for external I2C components, connected to analog inputs A4 and A5.
N-channel MOSFET for regulating power to external radio modules (both Bluetooth and NRF24). The gate is connected to digital pin D3 of the ATmega328. D3 should be set HIGH in order to enable power to radio sockets.
Low power (2mA) LED diodes that are connected via solder jumpers. Jumpers need to be soldered in.
On the back of the board there is place for: BME280, a digital temperature, humidity and pressure sensor, an additional EEPROM, and SI114x ambient / UV light sensor.
There are few such boards available and none with this kind of versatility.
Fully Arduino compatible with Arduino PRO Mini 3.3V @ 8MHz bootlader.
This board is perfect for low-power applications. Identical - small - footprint as Arduino PRO. Only better. It is intended for sensor applications and can be used as an universal board for sensor node networks. Dimensions are 2 inch x 2.1 inch.
