been looking for the smallest possible configuration of sparkfun pieces for 1) tiny battery module that powers 2) bluetooth receiver that with a very small bit of code can 3) turn on an led module.
Looks like the lily pad has some individual components like (1)[DEV-13883] and (3)[DEV-13735], but the bluetooth receiver as well as central controller for processing i/o and executing code are a little difficult to find. not sure what the difference DEV-13264 and DEV-13883.
any advice or feedback is appreciated. height of the overall thing im trying to make isn’t an issue, but it ideally wouldn’t be wider than a quarter.
I am not sure we are going to have a microcontroller that will have those specifications and size requirements. The closest options we have would be the [SparkFun Edge 2 or an XBee3 Module like [this. The Edge 2 will be more of your conventional development board and has BLE capabilities with I/O pins broken out to control an LED. The XBee3 modules are a bit different since they are typically embedded into a larger system but you can program them as a microcontroller.
Both boards require a USB to Serial interface to interact with a computer to upload code or monitor output. The Edge 2 has a 6-pin FTDI header on board to easily connect a [3.3V FTDI Basic Breakout or a [Serial Basic Breakout. For the XBee, we have a few different boards that allow you to plug in an XBee module and create a USB to Serial bridge called XBee Explorers. You can take a look at all of our XBee Explorers and other XBee products in our [XBee Category. To get started with either of these boards, I would recommend taking a look through the various resources we have linked in the “Documents” tabs on their respective product pages.
