we have developed this board for our internal use. If there is some interest we might sell it on amazon.
any feedback on pricing?
Our small volume build of 5 was quite pricey.
The useful thing about this board is it sends power and ground to many, many connectors making it useful for wiring in sensors and peripherals.
Some pins end up as jst connectors and some end up as 0.1 inch pitch through holes (with power and ground nearby) so you can solder on your own header pins.
We also have a nicely color coded wiring harness for you to connect directly to your favourite outputs!
Some of the pins are buffered.
This board breaks out 5 serial ports.
One of the serial ports goes to an xbee format header with 3.3 v.
You have to supply this board with regulated 5v, it does have an inline thermal fuse.
It does have a powered square wave buzzer on the usual pin.
It has a built in voltage divider on an analog pin so you can measure supply voltage.
At the moment it doesnt break out any of the pads or pins underneath.
This has been really useful to us. I wonder how many other people in the world there are with similar pain points that prompted us to design this board.
Oh and of course it does work with teensy 3.2!
these are the pins we broke out:
S_GPIO3_PIN 6 //CN16 CS on teensy 3.2

// UART3_TXD pin 8 //CN8
// UART2_RXD pin 9 //xbee and CN7
// UART2_TXD pin 10 xbee and CN7
