Description PowerHub is a programmable multi-channel power management controller built around the ESP32-S3-WROOM-1U-N16R8 module. It combines 2.4 GHz Wi-Fi, 16MB Flash, 8MB PSRAM and a dual-core Xtensa LX7 processor for IoT control, automation and connected power distribution projects. PowerHub uses an STM32G031G8U6 coprocessor with multiple INA226 voltage and current monitoring ICs plus electronic switch control. This lets PowerHub manage the power state of several expansion interfaces, monitor power consumption and support low-power timed wake-up for the complete device. The PowerHub hardware provides USB Type-A, USB Type-C, two HY2.0-4P Grove ports, an EXT 2.54-16P bus, RS485 and CAN interfaces with 120 Ohm terminal resistor switches, plus DC input, 2S lithium battery input and PWR485/PWR CAN reverse power input. The kit version includes a removable NP-F550 battery for mobile or backup-powered deployments. Features ESP32-S3 main controller: PowerHub uses an ESP32-S3-WROOM-1U-N16R8 module with 16MB Flash, 8MB PSRAM and 2.4 GHz Wi-Fi. Precision power monitoring: STM32G031G8U6 and INA226 monitoring help PowerHub control and measure multiple output channels. Multiple power input modes: supports DC 9-20V input, 2S lithium battery power and PWR485/PWR CAN reverse power input. USB switching: the bottom USB Type-C port can be routed through internal switches to the front USB Type-C or USB Type-A port for peripheral expansion. Industrial communication: RS485 and CAN ports include terminal resistor switches and are useful for automation equipment and field devices. Expansion interfaces: two HY2.0-4P Grove ports and one EXT 2.54-16P bus make PowerHub practical for sensor and actuator integration. Human-machine interaction: PowerHub includes multi-channel status LEDs and three physical buttons. Mounting options: magnetic mounting, rear cross mounting holes, LEGO mounting holes and M2 screw holes support desktop, wall and prototype installations.
