Budget: 900 UAH Deadline: 3 days
What exactly do you need to consult about? How to put the Arduino bootloader there or how to upload the firmware at all?
Good day. I am assembling a board for ESP32 for the first time using a video from YouTube. The boards and components have arrived. I soldered SMD elements to one of the boards and am testing its functionality. Arduino IDE says that the programming mode is not enabled, but the LED on pin 2 occasionally lights up when I turn on the firmware upload mode. The difficulty is that I have set up 2 boards, one as a bootloader and the other as a device. I need consultation from a competent master in board assembly.

очень небрежно спроектирована схема, наверно так же и разведены платы,
чтобы теперь сказать возьмите припаяйте провод туда и туда и все заработает.., лучше все сделать заново, выбросить кучу ненужных деталей и все будет работать как часы
Так, платам треба було більш уваги ріділити. Схему интерфейсу USB-UART Не дивилася, але помилка у платы ESP32 не дасть працювати пристрою.
Development of a Flight Controller for Fixed-Wing UAVs An experienced Embedded Hardware Engineer is needed to develop a flight controller for fixed-wing UAVs. Tasks: develop the electrical schematic; design a multilayer PCB; select the component base; prepare Gerber, BOM, and Pick&Place for mass production. Main requirements: microcontroller STM32H743 or equivalent class; functionality similar to Matek H743-Wing V3 (without copying); compatibility with PX4 or ArduPilot; interfaces: CAN, UART, SPI, I2C, USB, PWM; support for connecting GPS, IMU, barometer, telemetry, and other peripherals; maximum use of components that meet NDAA requirements (without using Chinese components where possible). Mandatory when responding: describe your experience in developing Flight Controllers or other Embedded platforms; provide examples of completed projects; indicate which CAD systems you use (Altium, KiCad, etc.); specify estimated timelines and costs for completion. Preference will be given to contractors with experience in developing electronics for UAVs, robotics, or avionics.
There is a board with esp32, sim800l, mini 560pro 5v. It has two pulse inputs (coin, bill). 1. A 6-pin connector (mdb) needs to be made. 2. Integrate power into the board, it can be replaced with ti, Pololu D24V5F3 6-30V 3.3V / 1.5A, as a choice or integrate the existing module into the board. 3. Replace sim 800l with another module (the pins fit, but differ in places). Gerber files are available, there are no schematics, base jlpcb.
