The CH32V003 series offers a 32-bit general-purpose RISC-V microcontroller (MCU) based on the QingKe RISC-V2A core design, tailored for industrial-grade applications. It features a robust set of capabilities including a maximum system main frequency of 48MHz, versatile voltage support (3.3V/5V), and extensive peripheral integration. The MCU is equipped with 2KB of SRAM and 16KB of Flash memory, providing ample storage for program and data needs.

Features:

  1. Utilizes QingKe 32-bit RISC-V2A processor with support for 2 levels of interrupt nesting.
  2. Offers a maximum system main frequency of 48MHz for efficient processing. Includes 2KB SRAM and 16KB Flash memory for data storage and program execution.
  3. Supports dual power supply voltage options: 3.3V or 5V, enabling flexible system design.
  4. Provides multiple low-power modes such as Sleep and Standby to optimize power consumption.
  5. Features a 1-channel general-purpose DMA controller for efficient data transfer.
  6. Incorporates op-amp comparators, a 10-bit ADC, and various timers for precise control and measurement applications.
  7. Includes standard communication interfaces such as USART, I2C, and SPI for versatile connectivity.
  8. Offers 18 I/O ports with external interrupt mapping, enhancing flexibility for peripheral connections.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
