We have designed ESP32 SD card module – ATF. it can record data save file to SD card. It need you write arduino code. for example, you can receiver serial data write LOG file to SD card. You can read digital input sensor or temperature humidity sensor write to SD card. it’s easy integrate to home assistant by ESPHome. ATF design for home automation DIYer. The hardware use by ESP32-D0WD-V3 / QFN-48-EP(5×5) chip, support ESPHome / arduino IDE / MicoPython.
PCB size: 50mm*30mm
