AnthC Industrial IoT Controller: ESP32, RS485, 4-20mA, 7-28V, Raspberry Pi Form Factor

AnthC — Open-Source ESP32-S3 Industrial IoT Controller

AnthC (Anthilla Controller) is an ESP32-S3 controller for industrial and field IoT: it reads 4–20 mA sensors, talks RS485, switches loads, and keeps running on battery when the supply drops. Raspberry Pi footprint, so it drops into existing enclosures and DIN-rail mounts.

Open-source hardware, OSHWA certified (IT000013, IT000014). Schematics, Gerbers, BOM and STEP model are public on GitHub.

Key specs

Not included

• 1S LiPo battery (min. 1000 mAh, with built-in protection circuit)
• CR2032 coin cell

Getting started

1. Power the board from USB-C or 7–28 V on the J5 terminal.
2. Install ESP-IDF or the Arduino ESP32 core.
3. Select the ESP32-S3 Dev Module board and flash an example.
