I received the module beanflying had suggested. It looks nice. But because I think my power needs are a bit high(Arduino, sleepinĪ for an hour and then waking up and transmitting using a Lora RA-01. Then back to sleep. The transmition takes the most of the energy I guess even though it lasts only 2-3 seconds every hour), I'm thinking of adding a small solar panel. Can a solar panel get connected directly on this module? (with a 5.1V zener diode at the output of the panel?) It does have a charger with the TP4056 ic. I see there are solar chargers using this ic:https://maker.pro/arduino/projects/diy-solar-battery-charger I 'm thinking of it this way (in the picture you see the bottom side of the module): |
