Hi - I noticed in Sipeed M1W datasheet v1.1 on page 3 where Pin Map layout is
There are 4 additional WiFi pins:
Are they for data buffer transfers or it is interface similar to DM9051 which is SPI to WiFi ?
They told me WiFi on that module works with AT commands but UART transfer is very slow
so I am guessing those pins are used for faster transfers - but how.
Anyone could help me with the information and examples maybe?
