PCB ESP32

Job ID: 39804766

Budget: $250 – $750 USD

PROFESSIONAL PCB DESIGN ESP32

I have a working prototype of a control and monitoring device based on the ESP32 microcontroller with a multi-channel triac control system and temperature sensors. The prototype currently operates on a breadboard and requires redesign as a professional PCB ready for production and further testing. The schematic is provided in the attached PDF file.

Technical Data from the attached schematic:

Microcontrollers: 2x ESP32 (30-pin)

Drivers: 6x MOC3021M (opto-isolators)

Power Triacs: 6x BTA204S-600E

Power Supply: IRM-10-5 (AC/DC converter)

Sensors: 6x NTC 10kΩ

Protection components: fuses, varistor, Zener diode

Filtering capacitors and current-limiting resistors

Scope of Work:

PCB Design:

2-layer PCB

Integration of all components according to the schematic

Component placement compliant with EMC requirements

Isolation of low-voltage section (ESP32) from high-voltage section (230V AC)

Trace routing considering operating currents

Appropriate clearance and creepage distances for high-voltage parts

Connectors for ESP32 programming

External sensor (NTC) interface outputs

Technical Specifications:

Board dimensions approx. 100mm × 110mm (subject to optimization)

Application: heating/cooling control system

Power input: 230V AC with conversion to 5V/3.3V DC

Output channels: 6 independent triac channels

Communication: (ESP32), UART programming interface

Expected Deliverables:

Complete project files (KiCad/Eagle/Altium format)

Gerber files ready for manufacturing

Drill files and pick & place data

Updated BOM with part numbers

Assembly documentation

Requirements:

Experience with high-voltage (230V AC) projects

Knowledge of electrical device safety standards

Ability to design mixed-signal (AC/DC) circuits

Portfolio demonstrating similar triac control projects

Design only, manufacturing excluded
Deadline: 1–2 weeks
