PCB ESP32
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
Attachment: Similar schematic in PDF format
