Hardware UART API. RP2040 has 2 identical instances of a UART peripheral, based on the ARM PL011. Each UART can be connected to a number of GPIO pins as defined in the GPIO muxing. Only the TX, RX, RTS, and CTS signals are connected, meaning that the modem mode and IrDA mode of the PL011 are not supported.So potentially there are 5 accessible UARTs at any one time. You can enable each of the UARTs on the Pi4B by making appropriate entries in /boot/config.txt. See /boot/overlays/README for details. At the simplest add the following entry to enable UARTx. dtoverlay=uartx Share Improve this answer Follow answered Oct 10, 2019 at 21:21 joanRaspberry Pi 4 has four additional UARTs available. Only uart0/1 is enabled over GPIO pin 14/15 by default. The additional UARTs can be enabled through the device tree overlays.

I have an application where I need a serial port (ideally two) and WiFi, but have no use for Bluetooth. My understanding is I can remap the PL011 UART from the Bluetooth/WiFi module to pins 14/15, but while everything says you lose BT if you do so, much of what I've read has been vague on the effect if any on WiFi. board of education meetings near me

May 16, 2018 · UART is a hardware implementation that supports bidirectional, asynchronous, serial communications. It requires two data lines - one for transmit and one for receive. The transmit line of one device is connected to the receive line of the second device, and vice versa for transmission in both directions. A UART can only connect between two devices.
