PCI Express 2-Port
7203e
The 7203e PCI Express serial interface provides two optically isolated serial ports, each individually configurable for RS-232, RS-422, or RS-485. Each serial port utilizes a 16C952 UART with 128-byte Tx/Rx FIFOs that enables data rates to 460.8K bps for reliable high-speed communications in data-intensive applications. This high-performance UART includes 9-bit framing support and is register compatible with legacy 16550 software applications. In addition, the board derives a 62.5 MHz clock from the PCI Express link. This ultra-high-speed clock is divided by a flexible 8-bit clock prescalar with 1/8 steps to provide support for the widest range of standard and non-standard baud rates.

SparkFun Transceiver Breakout
RS-485
This is a breakout board for the SP3485 RS-485 transceiver IC, which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps. This board requires a very low amount of power and can operate from a single +3.3VDC supply.

Four And Two-Port Multi-Protocol RS-232/422/485 M.2 Cards
M.2-COM-4SM Family
The M.2-COM-4SM family of cards feature high performance 16C950-class UARTs. Available in 4-port and 2-port versions, each port is capable of communication speeds up to 921.6kbps in RS-232 (differential modes support speeds as high as 3Mbps) and has 128-byte deep transmit and receive FIFOs. Large FIFOs protect against data loss in multitasking operating systems, reduce CPU utilization, and improve data throughput, while reducing or eliminating inter-character or inter-packet pauses. The advanced integrated circuit with pre-scalar supports a wide variety of custom baud rates, and any rates not otherwise achievable can be supported via a custom factory-installed crystal oscillator (up to 10Mbps!).

SparkFun GPS Breakout
NEO-M9N, Chip Antenna (Qwiic)
The SparkFun NEO-M9N GPS Breakout with on-board chip antenna is a high quality GPS board with equally impressive configuration options. The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations witn ~1.5 meter accuracy. This breakout supports concurrent reception of four GNSS. This maximizes position accuracy in challenging conditions, increasing precision and decreases lock time; and thanks to the onboard rechargeable battery, you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

Plug & Play JTAG/SWD Microcontroller Debugger with Built In GDB Server & UART
Black Magic Probe V2.3
In most cases Black Magic Debug takes the form of a firmware for the Black Magic Probe hardware, and implements a GNU DeBugger (GDB) server.The Black Magic GDB server features: - Automatic target detection- No need for target specific configuration scripts- All protocol and target specific control is done through GDB monitor commands- No “software in the middle” like OpenOCD required- Easily scriptable thanks to the GDB scripting capabilities- Interface to the host computer is a standard USB CDC ACM device (virtual serial port), which does not require special drivers on Linux or OS X.- Targets ARM Cortex-M and Cortex-A based microcontrollers- Provides full debugging functionality, including: watchpoints, flash memory breakpoints, memory and register examination, flash memory programming, etc.- [Semihosting / Host IO support] as well as [Serial Wire Debug TRACESWO support].- Implements USB DFU class for easy firmware upgrade as updates become available.- Works with Windows, Linux and Mac environments.
