Page 7: Supported Radio Modules
For both order codes 2612019024001 (Proteus-e evaluation board) and 2612019022001 (Ophelia-I evaluation board), the board is equipped with the Proteus-e Bluetooth 5.1 radio module. These modules have the same hard- ware platform, based on Nordic nRF52805 chipset. No micro-USB connection cable is delivered with the evaluation board. -
Page 8: Functional Description
After the module is powered through the USB jack or an al- ternative power supply, the reset button should be pressed to ensure a clean start-up of the module. The evaluation board is equipped with the Proteus-e radio module (flashed ® with Bluetooth LE firmware). -

Page 18: Programming Interface
Depending on parasitic capacitance of host PCB, a capacitance of 12 pF may be a good starting value for 31 and Using standard firmware with Proteus-e, the external crystal is not needed. To enable use of the LFXO a custom firmware is required. 3.5.6 Programming interface The evaluation board provides a 2×10 pin connector to connect directly to a SWD flash... -
