Quick note, this is then panelization repo, head for the individual repos to get design files.
Thanks so much to PCBWay for sponsoring my first assembly run for this project, they deliver awesome quality assembly service as always with 6 perfectly soldered dual sided prototypes delivered at my door in less than 2 weeks from ordering. All components perfectly placed and good quality 4 layer pcb's. I love the look and legebility of the 0.9mm inverted silkscreen texts. They even pointed out some reccomended component replacements due to NRND bom items. So Look at this beautiful trio of boards ready for automating every dumb device in my house.
ESP-Home code examples are comming soon.
The uPLC (micro Programmable Logic Controller) is a compact (22x32mm) I/O controller powered by the ESP32, designed to automate various tasks around you. So far, three versions have been developed. All versions are generally 24V-tolerant for digital I/O, except for the analog inputs, and feature a wide-range 3.8-24V buck regulator for power input.
The primary purpose of the uPLC is to "smartify" devices by integrating them with ESPHome. But it can also function as a direct, point-to-point PLC, using ESP-NOW for wireless communication, replacing traditional wired connections at a cost of latency.
- uPLC-Digital: High-speed digital I/O
- uPLC-Relay: Relays and digital I/O
- uPLC-Analog: ADC and DAC
- uPLC-COMM: For sensor connections- SPI, I2C, SDI12 support
- uPLC-4_20: Current loop for industrial sensors
- uPLC-TBD: If you have a good idea give me a message or issue
| Parameter | Description |

| Current Consumption | TBD: WiFi Active: ##mA, Radio Off: ##mA, Deep Sleep: ##uA |
| Communication | 2.4GHz Wi-Fi, UART (TTL level) |
| Baud Rate | 115200 |
| PCB Size | 22 x 31.1 mm |
| PCB Material | 1.6mm FR4, HASL lead-free, 4-layer |
| Case Size | X x X x X mm (TBD) |
To facilitate manufacturing and development, I've created a panelized version using KiKit scripting. The uPLC-Stack includes two units of each version, making it easier to assemble and test multiple variants in one go. Im planning on
To use the panelization script, clone all the uPLC repositories and organize them in a directory one level back from the uPLC-Stack folder. This allows the KiKit script to automatically pull in all required files for panelizing.
