Ant USB-C LiPo Charger on Tindie
https://www.electronics-lab.com/ant-usb-c-lipo-charger-tindie/
The USB-C has been around for quite a while, but there is still a lack of a miniature basic USB-C chargers for LiPo battery. I decided to make my own with as minimal footprint as possible, which resulted in being 13.5mm x 16mm. A well known MCP73831T-2ATI/MC is used as a battery charger in DFN […]
2x LiPO Battery to 12V and 5V Converter

Lipo Charge/Boost/Protect board in 18650 cell holder format
https://www.electronics-lab.com/lipo-charge-boost-protect-board-18650-cell-holder-format/
Peter6960 published a new build: So couple months ago, GreatScott made a video where he designed a circuit. Nothing too innovative, just the same TP4056 charger the MT3608 Boost combined on one PCB. He did add a Lipo protection circuit though, initially using the same DW01. But then, the Aha moment from this video, he […]
SODAQ ONE board – GPS + LoRa + Solar charger

Boris Landoni @ open-electronics.org presents their second version of Torpedo, a kind of DC-DC converter able to provide 5V output from a variety of sources. He writes: Some time ago we had introduced you to the Torpedo switching power supply, a particular kind of DC/DC power supply called SEPIC capable of supplying 5 V from several […]
Versatile And Open Source LiPo bBattery Breadboard Power Supply
https://www.electronics-lab.com/versatile-open-source-lipo-bbattery-breadboard-power-supply/
Orlando Hoilett from Calvary Engineering LLC designed a versatile Li-Po battery breadboard power supply and wrote an Instructables on it. This power supply outputs 3.3V to the breadboard and takes input from a single-cell LiPo battery. The breadboard power supply also has the ability to charge the battery without needing to separate it from the circuit board. More importantly, this […]
A 32-BIT FISHINO board with WiFi, SD card, RTC, audio codec, LiPo and more
https://www.electronics-lab.com/32-bit-fishino-board-wifi-sd-card-rtc-audio-codec-lipo/
Boris Landoni @ open-electronics.org presents his 32bit Arduino Compatible board which has some nice features on board. He wrties: Our prototyping board acquires a 32-bit processor and sets the bar high, towards demanding applications that may take full advantage of the WiFi support, of the RTC and of the SD-Card, that make Fishino stand out from […]
Solar Power Module v2
https://www.electronics-lab.com/solar-power-module-v2/
Chip McClelland @ hackster.io published his solar li-po battery charger based on MCP73871 to manage the solar and DC charging of the LiPo battery, TPS63020 Buck-Boost Converter and Maxim 74043 LiPo Fuel Gauge. He writes: I build connected sensor which are often deployed in local parks where there is no access to utility power. Over the […]
