Very pleased to announce this new breakout/carrier board kit that provides a neat and compact and prototyping/development set-up with nRF24L01+ support for the PJRC Teensy 3.0 or 3.1. Also convenient support for breadboarding and expansion using proto board via the second 0.1″ grid-aligned set of headers. All through-hole parts for easy soldering (as with all our kits).
All the pins on the Teensy that correspond to the Uno R3 shield layout pins are directed there, with the Teensy 3.x “superset” pins (A6-11, A14/DAC etc.) broken out onto a separate header. On the latest version of the board, the pins accessed by the underboard “pads” are optionally broken out using a 2×7 pin header. (Note however that Paul Stoffregen, the designer of the Teensy boards, warns that these pads weren’t really designed to sustain frequent plugging/unplugging, so care must be taken when using this approach. See here.)
The new Teensy 3.1 is an upgrade to the already extremely impressive Teensy 3.0, the most notable new feature being 5V tolerant IO pins. Bang for buck, there probably isn’t a better ARM-based X:duino dev board hardware deal out there. So how could we resist? A way of easily integrating these into your RFX or other nRF24L01+ related project made for too compelling a proposition to ignore.
I think the Teensy 3.x with RFX gateway solution is a killer price/performance solution for multi-project wireless Internet connected situations. You get the power of the Due with a Wifi shield attached (actually, much more than this) for a fraction of the cost per node.
Scalability! For basic applications, use a cheap and cheerful 328p device. For more resource intensive applications, and for not many $$$ more, a Teensy 3.x is an attractive choice. In between? Attach a RFX shield to a Mega2560, perhaps…
But also watch this space for future announcements. :-)
