Overview
This Yahboom sensor expansion board converts the pins of the supported controller board into multiple 4-pin PH2.0 ports for fast, tidy sensor wiring. It expands all the pins on the Micro:bit / Raspberry Pi Pico 2 / Raspberry Pi Pico / Arduino UNO board, with each adjacent signal pin paired with VCC and GND to form a 4 Pin PH2.0 interface for connecting sensors via a PH2.0 cable. Servo pins are also provided for connecting servos.
It is designed for the Yahboom World of Module Series sensor ecosystem and is also stated to support Yahboom general sensor modules and other sensor modules using a common PH2.0 interface. For pre-sales and compatibility questions, contact support@rcdrone.top.
Key Features
- Micro:bit is easily plugged into this expansion board.
- Supports World of Module series sensors; PH2.0 cable fast connection.
- PH2.0 interface is adopted to effectively prevent reverse connection (anti-reverse interface).
- Digital/analog interface support.
- Support IIC.
- Support PWM.
- Servo pins support driving a variety of servos (examples shown: 9G servo, 9G Metal Digital Servo, building block servo).
- No jumpers and soldering required; plug and play, designed to reduce messy wiring and reduce the chance of reverse connection and damage.
- Compatible with Yahboom World of Module series and 3 in 1 series sensor modules.
- Brick holes are reserved and can be combined with bricks to build different shapes.
- Three sensor expansion boards support three different boards (versions for Raspberry Pi Pico 2/Pico, Arduino UNO, and Micro:bit).

Turn your controller board pins into tidy 4‑pin PH2.0 ports for quick plug‑and‑play sensor wiring.
Choose the version that matches your controller board—separate options are available for Pico 2/Pico, Arduino UNO, and Micro:bit.
PH2.0 cabling keeps builds cleaner while supporting common interfaces such as digital/analog, IIC, and PWM.
Connect multiple sensors at once using standard 4‑pin PH2.0 leads designed to help prevent reverse connections.
Works across the Yahboom module ecosystem, including modules that also offer alligator clip or Dupont wiring options.
Dedicated servo headers make it easy to power and control common servos from the same expansion board.
No jumpers or soldering required—modules plug in directly so prototypes come together faster.
Project ideas include lighting, distance measurement, and alert builds using different controller boards and modules.
Keyed PH2.0 connectors help reduce wiring mistakes and protect components during frequent classroom or lab use.
The same PH2.0 module approach scales from beginner-friendly Micro:bit projects to Arduino UNO prototyping.
Micro:bit projects can be built in MakeCode with simple block programming and quick PH2.0 hookups.
Arduino UNO setups can be programmed in C/C++ while keeping sensor connections consistent through PH2.0 ports.
