Dual-Band Wi-Fi 6 Meets Industrial Automation: Meet the Maker Go ESP32-C5 EVB
Share
Building smart relay controllers or industrial telemetry nodes on 2.4 GHz Wi-Fi can be a risky game. Between heavy machinery interference, overcrowded routers, and signal dropouts, standard microcontrollers often struggle in noisy industrial environments.

Maker Go is officially solving that connectivity headache.
Their newly released ESP32-C5 EVB is one of the very first industrial-grade evaluation boards built around Espressif's long-awaited ESP32-C5 RISC-V processor. By combining dual-band Wi-Fi 6 (2.4 & 5 GHz) with heavy-duty relays and opto-isolated inputs, it brings high-speed, interference-free wireless control straight to your electrical cabinet.
The Powerhouse Core: Dual-Band Wi-Fi 6 & RISC-V
At the heart of the board lies the single-core, 32-bit RISC-V ESP32-C5 processor (clocked at up to 160 MHz). But its radio capabilities are the true star of the show:
- 5 GHz Wi-Fi 6 Capability: Finally lets your automation projects jump onto clean, low-latency 5 GHz networks to dodge 2.4 GHz band noise.
- Wi-Fi 6 Power Efficiency: Utilizes Target Wake Time (TWT) protocols to drastically reduce idle power consumption when monitoring periodic sensor states.
- Bluetooth 5.0 (LE): Simplifies local device setup, smartphone pairing, and mesh networking.
Heavy-Duty Control: 4 Relays + 4 Isolated Inputs
Maker Go didn't just build a breakout board—they built a complete, self-contained automation hub that handles real-world high-voltage equipment safely:
- Four Mechanical Relays: Onboard relays let you safely switch AC/DC loads (such as solenoid valves, lighting circuits, water pumps, or magnetic locks) directly from code.
- Four Opto-Isolated Inputs: Digital inputs route through optocouplers to physically isolate high-voltage sensing lines from the delicate ESP32-C5 silicon, protecting your chip from voltage spikes and ground loops.
- Status LED Matrix: Individual LEDs light up alongside every input and output channel, giving you instant visual feedback on signal activity during field maintenance.
Industrial RS-485 Communication
For factory floors and legacy building management systems, wireless isn't always enough.
The Maker Go ESP32-C5 EVB features a dedicated RS-485 serial interface with screw terminal connections. This makes it effortless to poll data from industrial Modbus RTU energy meters, PLC logic lines, or long-distance sensor arrays over simple twisted-pair cables.

Power Flexibility & Form Factor
- Wide DC Input: Accepts standard industrial power supplies (typically 9V to 24V DC) alongside a convenient USB-C port for fast desktop debugging and flashing.
- Standard Terminal Blocks: All relays, inputs, and serial lines use heavy-duty screw terminals to firmly clamp field wiring in place.
- Open Software Compatibility: Program it seamlessly using official ESP-IDF tools or standard Arduino IDE libraries.
The Verdict: A Modern Upgrade for Smart Infrastructure
Whether you are an automation engineer upgrading legacy relay panels, an e-commerce brand developing custom OEM controllers, or a maker building high-reliability smart home automation, the Maker Go ESP32-C5 EVB checks every box. It takes the game-changing reliability of dual-band Wi-Fi 6 and wraps it in industrial-grade armor.
