Its main chip is the ESP32-C6-MINI-1/U, from the ESP32 family. Other key parts include the SMXS-02K-TP, MCP73831-2-OT, XL1509-5.0 and AMS1117-3.3. By type, the board carries 14 capacitors, 11 resistors, 10 connectors, 10 diodes, 6 ICs and 3 switches.

It belongs with the iot & wireless, rf & radio and power & battery designs in this gallery.

From the project

A0 IoT Gateway

A0 is the base board of the modular A0 IoT gateway, built around an ESP32-C6 module (RISC-V, Wi-Fi 6, Bluetooth 5, IEEE 802.15.4).

The ESP32-C6 is Espressif's first Wi-Fi 6 SoC, integrating 2.4 GHz Wi-Fi 6 (802.11ax), Bluetooth 5 (LE) and IEEE 802.15.4 (Thread/Zigbee) radio connectivity in a single low-power chip (product page).

Wi-Fi 6 features (OFDMA, MU-MIMO, TWT) deliver low latency and long battery life even in congested RF environments, while combined Wi-Fi + BLE + 802.15.4 support makes it a natural fit for Matter end-point devices, Thread Border Routers, and Zigbee bridges.

A0 IoT GATEWAY: common questions

What microcontroller does the A0 IoT GATEWAY use?

The A0 IoT GATEWAY is built around the ESP32-C6-MINI-1/U, from the ESP32 family.

How big is the A0 IoT GATEWAY PCB?

The A0 IoT GATEWAY measures 54.6 × 86.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the A0 IoT GATEWAY?

57 components, from 34 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the A0 IoT GATEWAY design files?

From the absmach/a0 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the A0 IoT GATEWAY design in my own project?

Yes, under the terms of its Apache-2.0 license, which absmach chose for the repository.

Can I test firmware for the A0 IoT GATEWAY without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
