It does have 8MB PSRAM: I (882) spiram: Found 64MBit SPI RAM device Should be the latest batch of WiFi only devices from Fasttech have the new WROVER module with 8MB PSRAM. The kits with modems are still 4MB. Regards, Mark

Hello all, Thank you all for the great work developing OVMS, This is really neat!!
I'm not sure if my new v3 hw that arrived today has the larger PSRAM. Maybe this one still has 4Mb, see below?
In any case, .008 updated OTA successfully. Factory image was .002 Just connected it to home wifi. Nice job everyone! Thanks!!
