This board enables connecting buttonsswitchesencoders, potentiometers,  rotary switchesjoysticks  and various sensors, to easily deploy wireless solutions.

 

An battery charging circuit allows you to power the board with a battery for embedded applications, along with an internal connexion in order to measure precisely the battery voltage, so you will know the charge that's left.

 

You will have access to 22 I/Os, including 7 analog inputs with a 12 bits ADC. One additionnal analog input is available internally to measure the battery's voltage, as well as a digital input for the on board user switch. The inputs are 3.3 V and are not 5 V tolerant. The heart of this board is the NRF52840, the most suitable microcontroller on the market for embedded systems. Clocked at 64 MHz, it also offers 2 SPI ports, 1 I2C port , and 1 serial port. Like all the boards we propose, we have enhenced the kernel in order to offer as much features as possible. 

 

Note : This board is not using the bluetooth protocol, you will have to use a NrfDongle dongle to make it use it.
