This is a circuit module for a fridge magnet implementation. This can be integrated with a 1.54" ePaper display and housed in a 3D printed housing (embedded with magnets) to stick on a metal (ferromagnetic) surface. The central processor is nRF52840 which communicates over BLE to receive information from a BLE server running on another device and displays the desired information on the ePaper module.
