Description

The WeAct Studio CH582F Motherboard is built around the WCH CH582F system-on-chip, featuring a RISC-V architecture microcontroller optimized for Bluetooth Low Energy (BLE) communication. The board provides a complete development platform with direct USB programming and debugging, eliminating the need for external debuggers. Its integrated power management supports a wide input voltage range and includes protection circuits for reliable operation in field deployments.

With 448KB of ROM and 20KB of RAM, the CH582F is well-suited for firmware implementing BLE profiles, sensor data aggregation, and control logic. The inclusion of multiple serial interfaces (UART, SPI, I2C) and analog inputs makes it a versatile core for creating custom wireless sensor nodes, HID devices, or smart home controllers that require a balance of processing capability and ultra-low-power wireless connectivity.

Key Features

  • RISC-V 4A core delivers 60MHz performance for responsive BLE stack and application code execution.
  • Bluetooth 5.0 radio provides enhanced data throughput, extended range, and improved advertising packet capacity compared to BLE 4.2.
  • Dual-role USB port (Device/Host) enables easy firmware flashing via USB-CDC and connection to USB peripherals.
  • Rich I/O complement includes 4 timers, 10 PWM outputs, 8-channel 12-bit ADC, and multiple serial communication buses.
  • Onboard 3.3V LDO regulator delivers up to 100mA for external sensors, with input diode protection against voltage backflow.
  • Compact form-factor motherboard design exposes all critical GPIOs for rapid prototyping and system integration.

Applications

  • Bluetooth HID Devices: Keyboards, mice, game controllers, and presentation remotes.
  • Wireless Sensor Nodes: Environmental monitoring (temperature, humidity) with BLE gateway connectivity.
  • Smart Home Peripherals: BLE-controlled switches, lighting, and proximity-based automation triggers.
  • Wearable Tech Prototypes: Fitness bands, smart tags, and health monitoring gadgets.
  • IoT Data Bridges: Serial-to-BLE bridges for legacy equipment modernization and data logging.

Frequently Asked Questions

How do I program the WeAct Studio CH582F motherboard?

The board is programmed via its integrated USB-CDC port using the WCH-provided toolchain (MounRiver Studio or Arduino IDE with appropriate core). Connect via USB-C cable, install the CH582 driver, and flash your compiled BLE application firmware directly without an external programmer. The USB interface also supports serial debugging output.

What is the difference between Bluetooth 4.2 and 5.0 on the CH582F?

The CH582F supports the Bluetooth 5.0 specification, which offers significant improvements over 4.2, including double the data rate (2 Mbps), quadrupled advertising packet capacity for better broadcasting, and enhanced range via coded PHY. This makes it suitable for applications requiring faster data transfer, more complex beacon networks, or longer wireless links in IoT deployments.

Can I power the board and peripherals from the 3.3V LDO output?

Yes, the onboard 3.3V LDO regulator can supply up to 100mA to external low-power sensors or logic circuits. Ensure your total current draw from this rail, including the board's own consumption, stays within this limit. For higher-power peripherals, provide a separate regulated 3.3V supply directly to your external circuit.
