You’re problem is not that the chips have 1 UART. The problem is that you stick with only what you know. First problem is the Arduino is obviously expensive. 30$… ...

The new Arduino hardware offers a small and straightforward USB to UART converter with digital isolator, working between 2.5V and 5V up to 3Mboud, complete with an Arduino Pro mini connector.

It can be done, if you don’t mind (at least) tenfold bit rate reduction. If you set the uart to 8,N,1, than you know that long strings of back-to-back characters will have a 10 between the ...

Prestissimo Uno+ Arduino dev board with extra I2C UART SPI ADC IO and PWM channels. 2:24 pm November 5, 2018 By Julian Horsey.

The Arduino Nano and Raspberry Pi Pico support different input voltages, so they also use different power sources. However, they can both be powered with a 5V supply via their onboard USB ports.

The associated demonstration code continually streams increasing integer values through the Arduino UART to the transmitter, and receives them back via the fibre link. “To show this running, we put a ...

Introduction:In Arduino environment, it's convenient to access BT SPP like a serial port and react to the command string sent from the BT serial port. Many Arduino projects have utilized this way ...
