Raspberry Pi Pico はn コーディングと電子工学を学ぶための安価な方法。 Picoを購入した後、その範囲を拡大するために追加のコンポーネントも購入する必要があり、これは費用がかかり複雑になる可能性があります。 Maker Pi Pico は、プリはんだ付けされた Raspberry Pi Pico を含め、10 ドル未満の小さなパッケージに多くの追加機能を詰め込んでいます。
10 ドルで、機能の数は驚くべきものです。マイクロ SD カード リーダー、ブザー/3.6mm オーディオ ジャック、NeoPixel、すべての GPIO ピンが使用のために分割されており、互換性のあるコンポーネントで使用するための 6 つの Grove コネクタがあります。各 GPIO ピンには、問題をすばやくデバッグするために使用できる便利な LED があります。付属の ESP-01 ヘッダーにより、基本的な Wi-Fi アクセスが可能になり、レビューを書いて以来、Cytron は Maker Pi Pico をワイヤレスに接続する方法に関する更新されたガイドをリリースしました。 10 ドルでこのボードに勝つのは難しい!
Arduino’ s first RP2040 powered board may be the last of the first wave of partner boards, but it is safe to say that it is the most anticipated. The Arduino Nano RP2040 Connect is the only RP2040 based board to come with onboard Wi-Fi, the same Wi-Fi as used in Arduino’s Nano 33 IoT and given that these two boards share the same pinout and form factor, the RP2040 is a drop in replacement.
The Arduino Nano RP2040 Connect is not just a “one trick pony” it also comes with an LSM6DSOXTR Inertial Measurement Unit, capable of measuring orientation, inertial forces and gestures, and the board also features a microphone for simple voice/audio input. The Arduino Nano RP2040 Connect is compatible with CircuitPython, MicroPython and C, but being an Arduino product the greatest compatibility and support is found in their IDE.
However, for a board this expensive, it is annoying that it lacks USB-C and our initial experience programming it was a challenge because of some bugs. And the initial documentation from Arduino on how to program it has been very poor.
Adafruit’s ItsyBitsy RP2040 is the middle child between the larger Feather RP2040 and the s maller QTPy RP2040. The board is a compromise; we have more pins than the QT Py RP2040, a user programmable button, and it is the same price as the QT Py RP2040. What we lose is a Stemma QT connector. Not a great loss, but the feature is nice to have.
The board resembles an Arduino Nano layout but it lacks the castellated edges found on other boards, so no surface mount soldering for this board. On the up side, we have 30 GPIO pins around the board and given that this board is still rather small, that is quite the achievement. ItsyBitsy RP2040 is the ideal board to be hidden away in a project, getting the job done with little fanfare.
Pimoroni’s Keybow 2040 is something special in the RP2040 range: a programmab le 16-key keypad, powered by the RP2040. This isn’t a board that you use to build a project, rather it is something that we integrate into a project. With 16 mechanical keys, each with an addressable NeoPixel LED we can build the Keybow 2040 into our daily workflow.
The board ships with Pimoroni’s fork of MicroPython with modules to use Keybow 2040, but you will only get the best from this board via Adafruit’s CircuitPython and its USB HID module. Using this we can assign keypresses, media keys and mouse movements to any of the keys, making short work of tedious tasks.
All the features you need without wasting a millimeter
Qwiic connector
Great choice of GPIO
Small size
Castellated edges
Only one I2C channel
The $10 SparkFun Pro Micro RP2040 is the cheapest model in SparkFun’s range and fo llows a classic design that resembles an Arduino Nano board layout which is at home in a breadboard and embedded into your projects. We have fewer GPIO pins than a Pico, but more than Adafruit’s QTPy RP2040 while retaining a small layout.
SparkFun’s Qwiic connector, compatible with Adafruit’s Stemma QT, enables us to use many of the compatible components such as sensors and displays with the Pro Micro and for $10 this is a Swiss Army Knife of a board that provides a cost effective and multi-purpose means to explore the RP2040 ecosystem.
