Need more than one USART

[Daliwan]

Hi, in our project, we need to apply 51822 as MCU to control other devices. But we need 2 USART ports. I wonder is there any product in nRF51 series that can do this. Thanks.

Hi Daliwan!

I'm afraid that neither the nRF51 or the nRF52 has USART (universal synchronous/asynchronous receiver/transmitter), only UART (universal asynchronous receiver/transmitter).

The only one with two UARTs is the nRF52840, which is yet to be released.

Best Regards

Joakim.

We need UART, not USART, sorry for that.

Then I'm afraid there is no other product with two UARTS than the nRF52840. Production variants of the nRF52840 is expected in Q4 2017.
