## Questions & Answers

**Q: does this device allow 5v or 3.3v on the input and output pins?**
A: Definitely not 5 volt compliant. According to the Raspberry RP2040 chip spec the maximum digital input voltage is IOVDD +0.3 VOLTS. Since the maximum IOVDD  is 3.63 volts, the absolute max would be 3.93 volts.

**Q: Does it come with pin connectors?**
A: mine came with two sets of header pins which you must solder in place if you wish to use them.

**Q: Can you use this with accelerometer to make a spirit level?**
A: Sure.  You would also need a display and a battery.  Or use a USB cable and display on a computer.  But this would be overkill if it weren't so hard to get old cheap chips these days.  It's fine for a one off, but if you're thinking of production, check out things like older PIC an AT-Tiny parts.  But if it's an actual spirit level you want, just buy one.  If this is for inside a vehicle or robot, beware that accelerometers can only detect level in an unaccelerated frame (such as stationary, or constant speed including no turning).

**Q: what board choice in Arduino for code uploading? Does not upload as Uno**
A: In Auruino IDE, go to board selection, board manager and search for Seeed RP2040 boards. Download and install. Restart Arduino for it to recognize new libraries.

### ⭐⭐⭐⭐⭐ 問題なく使えました。

### ⭐⭐⭐⭐ ​「ラズパイPicoの脳みそ」を指先サイズに。極小ゆえの熱には注意
*by M***A on December 23, 2025*

Raspberry Pi Picoと同じパワフルな「RP2040」チップを搭載しながら、切手サイズにまで小型化した傑作ボードです。 ​最大の魅力は、やはりこのサイズ感とUSB-C端子です。Picoでは大きすぎて組み込めなかった隙間にも余裕で収まり、Micro USBのストレスからも解放されます。また、本家Picoにはない「リセットボタン」と「BOOTボタン」が両方搭載されているため、プログラムの書き込み時にケーブルを抜き差しする手間がないのも、地味ながら開発効率を大きく上げてくれます。 ​ただ、この小ささにデュアルコアのハイパワーを詰め込んでいるため、負荷をかけるとかなり発熱します。指で触れて「熱っ」と感じるレベルになることも珍しくありません。密閉された狭いケースに入れる場合は、放熱への配慮が必要です。また、ピン数が少ないので、複雑な制御をするには工夫がいります。 ​とはいえ、3個セットでこの価格、そしてこの性能。キーボードの自作や、ちょっとしたガジェットの制御用として、道具箱に常備しておきたくなる優秀なマイコンです。
