The ESP32-S3 PowerFeather V2 board is an ESP32-S3 WiFi and BLE IoT board with an Adafruit Feather form factor that supports LiFePO4/LFP batteries, as well as Li-Ion or LiPo batteries, and up to 18V DC input for solar panel connection. As one could have guessed, it’s an update to the ESP32-S3 PowerFeather board introduced in 2024 with support for solar panel input, Li-Ion, and LiPo batteries. The V2 design is virtually identical, except it features an Analog Devices MAX17260 fuel gauge and a TPS631013 buck-boost regulator that keeps 3.3 V stable to add support for LiFePO4 batteries. Lithium Iron Phosphate batteries are said to be safer and longer-lasting than Li-ion or LiPo batteries, albeit at the cost of lower energy density. ESP32-S3 PowerFeather V2 specifications: ESP32-S3-WROOM-1-N8R2 SoC – ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz Memory – 512KB SRAM, 16 KB RTC SRAM Wireless – 2.4 GHz […]
