I’m working on a 6s lipo tester that works with nrf24l01. I use a fake Arduino Nano and a pcb. The problem is the overheating of arduino. I tryed to modify the schematic eliminating 12 v linear regulator and using 2s voltage (8.4v) directly for Vin but the overheating appears again. I use different setup for voltage partition: before with <1mA per cell and after with 2/4 mA.
