T-ZigBee with 4MB of ESP32c3 memory?

Does such a board exist? With just 2MB of memory, it is hard (perhaps impossible) to allow HTTP based OTA upgrades.

@papadeltasierra OK, this is odd. according to the schematics, the SPI flash chip has 32M-bit capacity i.e. 4MB and yet on boot the ESP32c3 claims just 2MB.

@papadeltasierra Aha, there is indeed 4 MB of flash! You need to use idf.py menuconfig and then set the Serial flasher config to 1Flash size 4 MB and then use Partition table to select a 4 MB usable partition table.
