It is designed for mobile robots, portable interactive builds and maker projects that need more connectivity than the main controller can provide on its own.The board expands your available ports with digital, analogue, OneWire, I2C and ultrasonic sensor connections, while retaining access to the native gold finger interface. It also includes onboard WS2812 RGB LEDs plus an IR emitter and receiver for status indication and remote-control style projects without extra modules.For untethered builds, the board includes a 3.7V 18650 battery holder with charging and discharging management, plus battery status indication. It can drive up to 4 DC motors and 6 servos, with servo power supplied independently from the battery to help keep the main controller stable during high-torque movement.The included Type-C to HY2.0-4P cable is intended to power a UNIHIKER M10, and a DFRobot product wiki is available for setup information. The package includes the multi-function expansion board and one Type-C to HY2.0-4P cable.Features:Comprehensive I/O expansion: Adds digital, analogue, OneWire, I2C and ultrasonic sensor interfaces.Native interface access: Retains the mainboard gold finger interface for existing connections.Mobile power system: Integrated 18650 battery holder with charging and discharging management.Battery indication: Onboard battery level indicator for checking power status.Motor drive: Supports simultaneous control of up to 4 DC motors.Servo drive: Provides 6 servo interfaces with independent battery-powered servo supply.5V I2C support: Includes a dedicated 5V I2C interface for higher-current peripherals such as HUSKYLENS.Onboard outputs: Includes two programmable RGB LEDs for status or visual effects.Infrared: Includes an IR emitter and IR receiver for infrared projects.LEGO-compatible mounting: M3 mounting hole spacing on the base is compatible with LEGO brick dimensions.Debug indicators: Status indicator lights show system power, charging and motor direction.Protection: Acrylic baseplate helps prevent accidental short circuits, and all I/O pins include electrostatic protection.Specifications:Operating voltage: 3.3V DCUSB-C interface input voltage: 5V DCGPIO extension - 3.3V GPIO from main board edge connector: x8GPIO extension - 3.3V Digital/Analog/OneWire GPIO: x6GPIO extension - Servo interface (powered by battery): x6GPIO extension - 3.3V I2C: x3GPIO extension - 5V I2C: x1GPIO extension - 5V Ultrasonic Sensor (Trig-Echo): x1Motor Driver: DC Motor Terminal Block x4HY2.0 4-pin interface: x1 (power for UNIHIKER M10)Battery Holder: 3.7V 18650On-board components - RGB LED (WS2812): x2On-board components - IR emitter: x1On-board components - IR receiver: x1Size: 65*88mmWeight: 200gA practical add-on for robotics, autonomous vehicles and portable UNIHIKER or micro:bit builds that need extra ports, motors, servos and battery power in one board. **Product Type:** Expansion Board ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDWL4CSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--0c74973ae58ea06fddce4c3b2059209a4c7e8aac/DFR1216-1.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDYb4CSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--296c624bc2f1e186dc0a793e87798231cd00e9cc/DFR1216_Dim_02.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDar4CSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a6bf29bab44930e4bf6ec0a5ba16b2a8d809a6d3/DFR1216_Back_03.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDcL4CSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--1679118011910498ab29067f09431907f67ebc3b/DFR1216_Detail_04.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDd74CSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--2f264d589226581100bf894b04fba801efe9ed22/DFR1216_Detail_05.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDe74CSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--5041cf52fa18671c19f7d3f7dd115b9bdf1abb68/DFR1216_Main_01.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).
