Simply send ASCII characters or raw HID reports over a 9600-baud serial connection, and the CH9328 converts them into real keypresses on the connected computer, laptop, or mobile device. The breakout includes a USB Type-C port for easy plug-and-play connection to a host device, plus a JST SH connector for solderless wiring to your microcontroller. Four on-board DIP switches configure the operating mode before power-up. Key Features UART to USB HID Keyboard – Converts serial data into standard USB keyboard keypresses USB Type-C Output – Plug directly into any computer, laptop, phone, or tablet 9600 Baud 3V UART Input – Works with hardware or software serial from any microcontroller or SBC 4 DIP Switches – Configure operating mode before power-up JST SH Connector – Solderless connection option (5V, GND, data in) 5V Power Output – Power your microcontroller from the USB host via the 5V and GND pads Reset Line – Hardware reset input for reliable operation DIP Switch Modes Mode 0 (SW 2, 3, 4 ON) – ASCII characters sent as-is; 0x1B triggers Enter key Mode 1 (SW 2, 4 ON; SW 3 OFF) – ASCII characters sent as-is, no special key mapping Mode 2 (SW 2, 3 ON; SW 4 OFF) – ASCII characters sent as-is; 0x28 triggers Enter key Mode 3 (SW 3, 4 ON; SW 2 OFF) – Raw 8-byte HID reports for full control over keypresses, key holds, and non-US keyboard layouts Tip: Mode 3 is recommended for most applications as it gives you full control over keypresses and supports non-US keyboard layouts. Use the Adafruit CH9328 library for easy Mode 3 integration. Ideal For Adding keyboard emulation to boards without native USB (ATmega328, ESP32, ESP8266) Automating keyboard input from a Raspberry Pi or other SBC Building custom macro keyboards or input devices Cross-device typing — have one computer type into another Package Contents 1× Adafruit CH9328 UART to HID Keyboard Breakout **Product Type:** physical ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkClhFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--da56d6ca002098b1ee7c6e231d2e5f507f29003f/image_ddd7fc65-13e9-4dbd-b55e-8496e9f8bbfd.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkClxFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--8d0f210bf1dbaf4ea7ecd67f1efa4d2b7c3c8131/image_ef8c7e8b-157e-4be6-8c2f-7dfaec9c02c8.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCmBFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--1c160e681079cafcb9daca41316770114296328d/image_edf79150-5b59-48dd-a727-f17eb2e149f8.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCmRFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--95df3251e9684b874490b19eb314353d3655a756/image_2b6869de-220f-4bf9-a880-5947bc362d08.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCmhFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--0f3a0701c62ade0e3cb17b7d7767b903044d4cd9/image_4f9c4ff9-1d97-4684-a2dc-77aec31b7eca.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCmxFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--ef878b5982bb776d3fd74eedbf428688e47c7114/image_45468109-937f-446a-81bd-b007333a5336.jpg) - [Image 7](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCnBFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--7b6e0989d93f2b289eb24833cb14336499dbc743/image_2476cc1a-b6a9-4168-aeeb-153b4719b110.jpg) - [Image 8](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCnRFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--33fc1eb0d5aeb971740d2c4489275b8b59a116c6/image_00fcc86c-ae61-45be-96aa-9ea8ce1a421a.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).
