Solar Power Manger BAT_IN: LiPo and FireBeetle
Andy_A 2025-06-30 20:06:00 392 Views2 Replies Hi there,
I'm planing to build an ESP32-S3 based battery powered project.
Planed (main) products are:
→ DFR0559 Solar Power Manager 5V (https://www.dfrobot.com/product-1712.html)
→ DFR0975 FireBeetle 2 ESP32-S3 (https://www.dfrobot.com/product-2676.html)
Q: Is it possible to connect like this:
LiPo (+) → Solar Power Manger (+) JST PH2.0
Lipo (-) → Solar Power Manger (-) JST PH2.0
Yes, it is possible to connect the DFR0559 Solar Power Manager 5V to the DFR0975 FireBeetle 2 ESP32-S3 as you described. You can connect the Solar Power Manager's positive (+) screw terminal to the FireBeetle's PH2.0 positive (+) terminal and the negative (-) screw terminal to the FireBeetle's PH2.0 negative (-) terminal. This setup should allow you to utilize the AXP313A power management chip on the FireBeetle 2 ESP32-S3 for monitoring the battery without needing additional components.
Tonny12138 I don't know why the CMS f* my post up like this…
Solar Power Manager (+) Srew Terminal → FireBeetle PH2.0 (+)
Solar Power Manager (-) Srew Terminal → FireBeetle PH2.0 (-)
The goal is to use the capabilities of the AXP313A for monitoring the battery without the need for other components.
The DFR0579 (https://www.dfrobot.com/product-1781.html) showing this kind of setup, but I'm not sure if also fit's for the “bigger” brother.
