Research on hardware selection
For the project, BLE hardware needs to be chosen. I’ve considered 2 options: using a ready-made BLE board and custom-made PCB.
motorized
BLE-based micro scale RC receiver
A 10x14mm PCB with nRF52 MCU
Motor control board
A small PCB to control motors in small-scale models. I’ve developed it as part of the portal crane.

Updates for February and March
So, here is what I’ve been doing for the past 2 months.
