For the GS1011 and GS1500 modules, there are two interfaces, SPI and UART. For the GS2000 based modules, there are 3 interfaces, SPI, UART and SDIO. Refer to GainSpan SDK Builder User Guide for more information.
- UART (Standard baud rates from 9600b/s to 921.6Kb/s Maximum) - baud rate for UART is 115200 (default). This could be enhanced to 921600, if GPIO25 is set high. No hardware flow control.
- SPI (Maximum 10MHz Slave, Maximum 30MHz Master). 2 SPI interfaces are available to the application and can be configured master or slave. Baud rate for SPI is 1.2MHz clock.
- SDIO (Maximum 40MHz). Slave mode only supported
