Choose the Right MeArm Controller
Partager
Not sure which MeArm controller is right for you? This guide breaks down each option by who it's designed for, what's included, and what skills you'll need — so you can pick the best fit and get building faster.
Controller Comparison at a Glance
| Controller Option | Best For | Included Hardware | Skills Needed | Shop |
|---|---|---|---|---|
| Raspberry Pi Pico – MeArm Controller Board | Makers comfortable with Python who want a compact, affordable microcontroller | Controller board (Pico sold separately); joysticks, servo connectors, USB | Basic MicroPython; comfortable flashing firmware | View product → |
| MeArm Controller Board for micro:bit | Educators, schools, and beginners — especially those already using micro:bit in class | Controller board with joysticks and servo ports (micro:bit sold separately) | Drag-and-drop block coding (MakeCode); no prior robotics experience needed | View product → |
| MeArm WiFi – Arduino Compatible Robot Arm Kit | Hobbyists who want a complete, ready-to-build kit with wireless control | Full MeArm acrylic kit, Arduino-compatible WiFi controller board, servos, joysticks, USB cable | Basic assembly; optional Arduino/C++ coding for customisation | View product → |
Which Should You Choose?
🟢 Start here if you're a complete beginner: micro:bit Controller Board
The MeArm Controller Board for micro:bit is the most beginner-friendly option. If you already own a micro:bit (common in UK schools), plug it in and start coding with block-based MakeCode — no soldering, no terminal, no prior robotics knowledge required.
🔵 Best complete kit out of the box: MeArm WiFi Arduino Kit
The MeArm WiFi Kit includes everything you need — the arm, servos, and an Arduino-compatible WiFi controller — all in one box. It's ideal if you want to build and control a robot arm without sourcing parts separately. WiFi control means you can operate the arm from your phone or browser.
🟣 Great for Python learners: Raspberry Pi Pico Board
The Raspberry Pi Pico controller board is a great pairing for anyone learning MicroPython. The Pico itself is inexpensive and widely available, and this board gives you a clean interface to connect joysticks and servos. Note: this is a BETA version — ideal for early adopters who are comfortable experimenting.
Common Questions
Arduino or Raspberry Pi — which is better for MeArm?
Neither is objectively better — it depends on your goals. Arduino (C++) is event-driven and well-suited to controlling motors and servos directly. Raspberry Pi Pico (MicroPython) is great if you prefer Python and want a compact, low-cost microcontroller. Both are capable of running the MeArm; the right choice is the one that matches your coding background.
Do I need to buy a separate micro:bit or Pico?
Yes — the controller boards for micro:bit and Raspberry Pi Pico are sold without the microcontroller itself. The MeArm WiFi Arduino Kit includes its own controller electronics.
Can I switch controllers later?
Yes. All MeArm kits use standard servo connectors, so the mechanical arm is compatible with different controller boards as your skills develop.
