This socket to program is the famous, yet smallest Bluetooth module (NRF24L01). It will allow you to connect NRF24L01 to Arduino Uno or any other 5V microcontroller. It has an onboard 3.3V regulator, so you do not have to be afraid of frying this board, because it can be powered from a 4.8-12V supply.
- Input voltage: 4.8V - 12V
- Small power-on LED indicator
