Meeting your every need for a robotic car, it can ensure that the onboard module resources are not affected after switching any version of the controller, and the sensor interface is compatible.Equipped with a wide range of sensor interfaces, such as ultrasonic obstacle avoidance, 2-channel infrared obstacle avoidance, 2-channel light-seeking, 4-channel tracking, RGB lights, color recognition, MPU6050 gyroscope and linear CCD camera. Compared to the traditional open IO port and DuPont line connection, we use a simple and easy to operate modular design and socket cable connection. It is easier and simpler to make the wiring not rough.3 motor drive capabilities, including 4-channel DC motor interface, 6-channel servo interface and fire-extinguishing fan interface.With 9.6V-13.5V wide voltage input, the voltage is lower than 9.6V, and the over-discharge protection circuit automatically cuts off the power to protect the battery. In addition, the board also has a 12.6V charging interface, 3.3V/5V voltage switching, reverse connection protection, voltage monitoring circuit, forced reset circuit, low voltage prompt and stalled restart circuit to provide a stable power supply system.Support 6 kinds of communication methods: Bluetooth interface, WiFi module interface, 24L01 wireless interface, SPI communication interface, infrared receiving (integrated) and CH340 serial circuit (integrated)Support 5 kinds of control methods: mobile APP, PC computer, PS2 controller, infrared remote control and gesture armband.Feature Compatible with four controllers Abundant sensor interface Strong motor drive capability Stable power supply system Multiple communication modes, Bluetooth APP provided Strong expansibility DetailDocumentsYahboom 4WD expansion board **Product Type:** physical ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCeTFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--2740cd359ea017bfe54620675859b053870c1d58/image_89381f25-5114-4069-bcb7-b00d48416cc3.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCejFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--866fb6ed3f90758c6689d163f3691591932fa6d0/image_58d1feb2-4929-4352-8735-ee62f9378e50.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCezFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--108406542b56a8d1e1761334c1367296f7ccded1/image_b7cb22d6-9ccf-4722-887d-213baaf107c3.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCfDFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--12f0b5b794c05541c0988e1eb4e8e74a6c71f35d/image_50b74daa-7f05-49dd-99b5-2d4ec7821883.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCfTFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--de43e1db420d658316a1590b426cc9af7cba9244/image_730f5147-da75-4fca-b913-8f8fd8ea2f4a.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).
