Hi, I finished the implementation and documentation of the OVMS module based on the Lilygo T-Call A7670E board (ESP32 WROVER E and a Simcom A7670E). The module is in operation since more than a month in my Smart EQ. The hardware details can be found here: https://github.com/zbchristian/OVMS-Lilygo-based-Module There are some limitations wrt the standard module: - only 4MB Flash -> no OTA update - no GPIO extender -> only 2 CAN buses - no SD-card support The required modification in the firmware: - remapping of the ESP32 pins in ovms_peripherals - replace some of the GPIO extender pins by standard ESP32 pins - new hardware option in menuconfig (set CONFIG_OVMS_HW_BASE_LILYGO_1_0=y) - Simcom 7670 modem support (already available in the OVMS repo) All this is available in the branch lilygo-support of https://github.com/zbchristian/Open-Vehicle-Monitoring-System-3-Lilygo-Suppo... My question to the main developers: Is there interest to incorporate this into the official OVMS repository? Best regards Christian
