Need to make a device similar to an electronic relay. I do not know the correct name for this device, whether it is a switch, relay, trigger, or something else.
There is a digital logic output from ESP32, which can have values of 0 or 3.3 Volts. This output serves as the control for the device. There is a 5V power supply, which is fed to the device, and depending on the presence of control voltage at the output, it should be either 0 or 5 Volts.
The device should be mounted on a board, with possible surface mounting. The size of the board is 15x20 mm. The height should not exceed 7 mm.
The price is indicated as a rough estimate. The deadlines are preferably as soon as possible.

Ось варіант для вас. https://arduino.ua/ru/prod2871-tlp281-4-channel-opto-isolator-ic-module або https://arduino.ua/ru/prod5926-mini-pushbutton-power-switch-with-reverse-voltage-protection-lv
А може подивитись що таке биполярний транзистор або мосфет )) на ютуб
І ваше питання зникне.)
Доброго дня. Варіантів вам накидали багато і всі в принципі робочі, які у вас є додаткові побажання?
Я так розумію у вас має бути 3-контакта: вхідна напруга (0-3.3), земля, вихідна напруга (0-5). Так?
Який максимальний струм? Контакти потрібно припаювати чи прикручувати через якийсь конвектор?

It is necessary to integrate the NCS with the automatic launch system (catapult with a microcontroller) to transmit a signal to the microcontroller, which will initiate the operation of the catapult 500 meters away from it.
Create compatibility between the ground control station, automatic start system (SAS), radar, and the aircraft.
It is necessary to refine the existing Bitclock rev3 PCB in KiCad. Project sources: https://github.com/goat-hill/bitclock/tree/master/bitclock-pcb/rev3a/kicad Task: 1. Change the size and shape of the board to fit the new STEP/3D model of the case. 2. Move/replace the current power connector with USB-C. 3. Redesign the monitor connection port to an 8-pin connector. 4. Arrange components so that the board fits correctly into the case according to the mounting points. 5. Preserve the existing functionality of the board. 6. Check the alignment of the board with the 3D/STEP model. 7. The output should include ready KiCad files + updated 3D model/fit check. Main requirement: a specialist in KiCad/PCB design is needed, who can work with STEP cases and mounting points.
