Processor

[Rigs]

Hi All - just interested in what's at the heart of NDLR  - what processor is inside?

Caught one of the early videos which mentions Cortex M0 - but also mentions a possible upgrade for future expansion - what was the final choice?

Thanks

We started with something smaller, but ended up using a PJRC Teensy 3.2 based design. Its fast, and with the PJRC bootloader, the NDLR is practically unbrickable.
Here's what it looks like on The NDLR circuit board... The "Teensy" is circled in green.

Many thanks for that - it's always interesting to know what's under the bonnet so to speak. The Teensys seem to be appearing all over the place - powerful liitle units.

The new Teensy 4, and the other new Teensys coming in the next year or so are incredibly fast. The Teensy 4 even costs less than the Teensy 3.6.

Its quite a great time to be developing smart widgets. With Teensy, you also have the option to develop on more advanced IDEs, like VSCode or Platform.io. PJRC and their team of contributors have created a fairly robust software library. It saves a lot of time, so we don't mind paying the "tax" for the PJRC boot loader MCU. However, there are times that the code must be enhanced for performance or suitability to the task. We'll give back to PJRC when we make improvements.
