I've been diving deep into bluetooth audio over the past year, going from the Microchip RN-52 to the BM-62/64, and now the BM-83. The problem with the BM-83 is that you can either get the bare chips, or a $350 development board for MC. As to not break the bank, I was going to make my own boards, but I managed to come across this amazing breakout for the BM-83. It's preassembled, fits into a breadboard, gives access to all the pins, and doesn't have any excessive components. A very simple and well executed breakout board that I would have willingly paid more for. You can't go wrong with this board. Even as picky as I am with components and designs, this is perfect.
I originally bought this as a convenience for some Dotstar LEDs I was working with (for which purpose it worked flawlessly). Since then it’s become an essential component in my prototyping work. The dual connection points (headers and terminal blocks) are so convenient and easy to access, and the ability to quickly change voltage has saved me so much time. Highly recommended as an essential part of any RasPi prototyping toolkit.
I had a one-off project, bought a board and in a week, I had a fully assembled board, a great dialog going about my project, exceptional kindness, insight, and genuine interest in my project as well as a fully functioning board and example project to boot. That saved loads of time! Short review, but it's just short and sweet!
Great product. Compact and works well. Love all the power options and the fact that the voltage regulator is a daughterboard, in case it ever needed replacing. The seller also helped me out getting started with some example code on his github repo. I'll definitely be getting more at some stage
This is a well designed and quality built board, packaged well, and shipped super fast. A great development board for Teensy 4 because it manages to bring out all the hard to get at pads using a flex cable and some pogo pins.
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.
