I am developing a prototype device that can be implanted inside a test subject and transmit data to an external receiver. I need to locate an RF-equipped microcontroller that is small enough to fit on the implant hardware I currently have. Size is more of an issue than computing power, as the controller will be communicating with a limited number of sensor. If someone could point me in the right direction it would be greatly appreciated! I can also provide additional information as necessary.
Thanks in advance!
