It follows the bite-sized style of boards like the Adafruit QT Py and Seeed Studio XIAO, while adding SMD pins for optional extra IO and a built-in WS2811-compatible LED output.The CH32V203G6 has a single 32-bit RISC-V core running up to 144MHz, with 1-cycle multiply and hardware divide. It includes 10KB SRAM, 32KB single-cycle Flash, plus an additional 224KB of external XIP Flash that can be used for program or data storage, although it is not as fast as the 32KB Flash.You also get the expected embedded peripherals, including ADC, timers, USB device support, UART, I2C and SPI. The CH32V203 has a USB bootloader that can be activated by holding the button while plugging in the USB cable, or you can use a WCH-Link programmer and debugger via the exposed SWD pins.Please note that the CH32 series is not as well supported as ATmega, ESP32, ATSAMD, STM32 or RP2040 platforms. It does not run CircuitPython or MicroPython, and Arduino support is still very early, so this board is best suited to experienced makers and developers comfortable with Makefiles, Git repositories and configuration files.Features:Form factor: Bite-sized development board style similar to Adafruit QT Py and Seeed Studio XIAO.Extra IO: Added SMD pins for optional extra IO capabilities.LED output: Built-in WS2811-compatible LED output.Embeetle: Officially supported by Embeetle.Arduino core: SPI and I²C Master support since version 1.0.2.Platform.io: Requires your WCH-Link firmware to be updated to the latest version.CH32V003fun: Experimental support for the CH32V203 at the time of writing.MounRiver Studio: The official IDE supported by WCH, based on Eclipse.USB bootloader: Can be activated by holding the button when plugging in the USB cable.Debugging: WCH-Link programmer and debugger support via the exposed SWD pins.Specifications:Microcontroller: WCH CH32V203.Processor: Single 32-bit RISC-V core.Clock speed: Running up to 144MHz.Multiply: 1-cycle multiply.Divide: Hardware divide.SRAM: 10KB SRAM.Flash: 32KB single-cycle Flash.External XIP Flash: 224KB of Flash that can be used for program or data storage but is not as fast as the 32KB.ADC: Included.Timers: Included.USB device: Included.UART: Included.I2C: Included.SPI: Included.Github documentation: Available.Schematics: Available.BOM: Available.Certified Open Source Hardware: OSHW BE000018.This board is a good fit for experienced RISC-V and embedded developers who want a tiny CH32V203 platform with USB bootloading and SWD programming options. **Product Type:** Microcontroller Board ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDRNICSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--aba5777f517c0326947d423df1185860c2b7f3bf/6042-00.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDSNICSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--c4629042f10dee0cf518c7a71dcc1fd3c90fed6d/6042-03.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDTdICSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--3a2902f3e09ae08db20c046e2fe6a82f31a23c5c/6042-01.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDT9ICSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ed98ca0b115bfa9b17a48471aa9134651311fb54/6042-04.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDUtICSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--f4dbd811daa2a923b5bf9bb53e386f845e36d600/6042-05.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDVNICSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--2d8791c61f59db020f57b9f0ba0dfbe26209e399/6042-02.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
