Hi

Could you tell me the "Drive capability"(xx mA) of each PIN on CYBT-343026-01 module when it is set to output ?

Regards,

T.M.

The GPIO are capable of driving up to 8 mA at 3.3 V or 4 mA at 1.8 V. However for P26, P27, P28, and P29, they are capable of driving up to 16 mA at 3.3 V.

Hi

Thank you

In addition.

Is this same (8 mA at 3.3V) in the following the "special" PINs ?

PAD 6  SPI2_CS_N

PAD 9  SPI2_MOSI

PAD 16 UART_TXD

PAD 18 UART_RTS

Thanks

Usually we do not talk about electrical current levels for digital communications like UART. But I noted that for digital IO, the max output current at 3.3V is 4mA (Table12 of CYW20706 datasheet). You may want to download a copy of the 20706 datasheet for more information on this chip.

Hi

I understood it.

Thanks
