Description
The development board with Bluetooth Core51822 module based on the nRF51822 system. It is equipped with UART, I2C and SPI interfaces and USB to UART CP2102 converter. It works with a voltage of 3.3 V and 5 V. It has a battery slot so the module can be powered independently from an external source. The board consists of LED and buttons for use by the user.
|
For programming, the device requires an external programmer, for exampleARM-J-link. |
Set has BLE400 board, the Core51822 module and USB cable.
