Power supply for Arduino project
There is an Arduino project, connected to 2 load sensors through the hx711 load sensor control module, a panel board, on which the esp32 cam board and df3 player mini are placed, to which a 0.5W speaker is connected.
Also, a heating element is connected to all this through the IRF520 transistor module, and a temperature sensor DS18B20.
It is necessary to create a power supply that can be recharged; currently, there are 2 18650 batteries with cases that are connected in parallel to the tp4506 charging module. From the charging module, there is a kcd1 button with 2 pins, then there is a boost converter SX1308, and from it, power is supplied to the Arduino.
The problem is with the power supply; the Arduino does not want to work from it, the RX sensor on the board is blinking. It is necessary to ensure that the power from the batteries goes to the Arduino and to the heating element.

397 1 0 15 days300 USDI won't break down the task. The job is quite trivial. I don't like to rush with time. I took the maximum, but I think I'll submit it earlier. Work in Proteus with prototyping on models.

ESP32 имеет питание 3,3 В. Лучший вариант: соединить аккумуляторы последовательно (не забудьте балансир), поставить понижающий преобразователь на 3.3 В, запитать ESP32 напрямую (контакт +3V3). Не забудьте про режим сна для ESP32, с отключением всех ненужных потребителей. Это позволит продлить время работы устройства от аккумуляторов.

Доброго дня.
Яка потужність тена? Rx Tx блимають коли йде передача даних по uart. Можна зробити щоб живлення плати і тена відбувалось від акумулятора. Додатково вкажіть які акумулятори ви використовуєте, як варіант зробіть відео, це допоможе вирішити проблему.
