For simple console port access without JTAG programming, a simple USB to UART adapter can be used. Examples of these include the [[https://www.adafruit.com/product/5335|Adafruit CP2102N Friend]], [[https://www.sparkfun.com/products/18289|SparkFun Electronics KIT-18289]], and [[https://ftdichip.com/products/ttl-232rg-vsw3v3-we/|FTDI TTL-232RG-VSW3V3-WE]]. | For simple console port access without JTAG programming, a simple USB to UART adapter can be used.

**The console UART port operates at 115,200 bps, 8 data bits, no parity, 1 stop bit, and no flow control.** | **The console UART port operates at 115,200 bps, 8 data bits, no parity, 1 stop bit, and no flow control.** |

These boards can be built in either the {{oxygen:rwt_rf_personality_standard_pcb_drawing.pdf|standard personality board format}}, or in an {{oxygen:rwt_rf_personality_extended_pcb_drawing.pdf|extended personality board format}} if more pcb surface area is needed for components. A {{oxygen:rwt_rf_personality_schematic_template.pdf|schematic template}} has been created to illustrate the pinout of the mezzanine connectors, how these pin numbers map to the socket connectors, and the power rails that are available. | These boards can be built in either the {{oxygen:rwt_rf_personality_standard_pcb_drawing_v2.pdf|standard personality board format}}, or in an {{oxygen:rwt_rf_personality_extended_pcb_drawing_v2.pdf|extended personality board format}} if more pcb surface area is needed for components.

A full pinout of JRF1 can be seen in the table below. The mezzanine connectors are hermaphroditic and the [[https://www.samtec.com/products/lss-120-03-f-dv-a-k|same part number]] is used on both the socket and the personality board. This results in even and odd pin numbers being swapped. For example, pin 1 on the socket will connect to pin 2 on the personality board. The JRF2 connector is optional and is currently used only for mechanical support and future expansion of the socket standard. There are no signals on it. | A full pinout of JRF1 can be seen in the table below.
