Description

This project is unsuccessful part of my "mWessenger" project, where I tried to use mW-oven leakage radiataion as energy source - the input power plus efficiency of overall circuit was too small to implement initial idea to power BLE module with it.

However, I still got couple of PCBAs and all design files, which can be used for other project :)

The PCBA consist of following parts:
1) energy harvesting circuit based on ADP5091 (can be reconfigured to different applications by changing values of appropriate components on PCB)
2) BLE module - BGM111 - with its ultra-low power consumption and p.1. already can be used as independent beacon
3) connectors for attaching power input (i.e. solar cell), storage element (i.e. LiPo) and even some auxiliary sensors (SPI, ADC, UART) / power consumers (Vbat and regulated output are available)

So, after realizing, that this PCBA is not suitable for my mWessenger project, I decided to reconfigure it just by replacing some resistors/capacitors/jumpers and use it for other purposes.
At the moment I'll post schematics in "as-it-is" stage, however, I plan to make it work with tiny solar panel and Li-Po battery. - Then I'll post all other files. Probably, I'll even design some enclosure for 3D-printing.

If you are interested in helping / joining this project - just let me know, I'll share design files already now with you ;)
