🚀 The Ultimate Teensy 4.0 (With Pins) – Unleash Limitless Possibilities Review

This is my pick for all my experiments, right price, superior processing power, best format for what it is and they can take a beating. I did a lot of soldering and desoldering and made various wiring mistakes and they always forgave them, rebooted and gone.

This is my choice for all my experiments, at the right price, with high processing power, the best format for what it is, and they may be defeated. I did a lot of soldering and desoldering and made various wiring mistakes and they always forgave them, rebooted and gone.

Small and fast. If you need a micro SD or more contacts, use version 4.1. The software is a slightly fancier form of Arduino. The speed is amazing for its size, but the amount of solder required to add some features can be a deciding factor for some. Max pin power is pretty low, so expect driver circuits to be needed for pretty much everything.

I would have preferred version 4.1 but my schedule didn't keep me waiting any longer. The product was delivered as promised and is fast enough to emulate other hardware I don't have. I enjoy working with the Arduino IDE, so writing the code for it was an easy task. Some direct I/O ports are not supported in the same way as on AVR devices. Some of the additional features aren't well documented, but there are plenty of examples, as is the case with most Arduino alternatives, and a forum for…
