I bought a few of these with the intention of making a few Bluetooth mouse projects, since it's stated that it has HID functionality: "Bluetooth Profile HID v1.1 SPP v1.2." Serial mode works. So that part is great, but not the part I needed. I messaged the seller a week ago, letting him know that I had been unable to get HID mode working and asking how it was supposed to be enabled. He quickly responded, saying he would try to get that part figured out and get back to me.
If anybody can help figure this out, that would be awesome too so I could change my review :)
This board was just what I needed. With a few modifications to Chris' example code, I was up and running the day I received mine. I was able to setup a series of temperature & humidity probes around the house, all of which log data via UDP to a local InfluxDB TSDB. There are plenty of options for how to use this board.
Chris has been extremely helpful and very responsive. Despite having lots of programming experience, the world of electronics and Arduino is still fairly new to me, and Chris has been quick to respond to my questions regarding the board.
With a built in 3008 chip and the ability to steal 5/3vdc from the bus this is a nice unit to get your ADC needs done quick. Fits right on top of the Pi and with the pass-thru connector you can connect more stuff to the top of the board. Who doesn't need more stuff connected to the top of a Pi? While I haven't completed my project I'm not far from getting it done. But this board popped right on top of my Pi and I was off to the races from there.
I find that this board does all that the description says. Two item that can be improved: 1. The 100 mil pitch holes for soldering the pin-row header need to have a larger annular ring to help increase solder-ability. 2. Ground and (5V) Power plane connectors need thermal relief internal pads to help with soldering.
Thanks to this board, I can quickly add different peripheral controls from Teensy 3.x
