Overview
MB9X UART is an open-source printed circuit board by famicomical, from the famicomical/MB9X-UART repository on GitHub. It is a 2-layer board of 36.4 × 31.8 mm with 15 parts on 32 nets, routed with 212 tracks and 5 vias.
It is built around the MAX232ID and BAT85. Its parts include 5 capacitors, 3 connectors, 2 resistors, 1 IC and 1 diode. It belongs with the interfaces and adapters boards of this library.
Main components

README.mdMB9X-UART
Allows you to program the Fujitsu F2MC-16LX series processors using an RS-232C serial port connection. It uses a 12-pin connector for direct connection to the JVC DT-V series monitors and an optional 10-pin connection as described in Fujitsu documentation. Note: programming the DT-V monitors requires modifying the Signal PWB.
The person assembling this board will need to procure their own USB to RS232-C cable and their own copy of the Fujitsu "FLASH MCU Programmer 16LX" software, which includes proprietary configuration files for the MCUs. I recommend installing ISP-MB9X by Sergey Pinigin in addition to the Fujitsu software to have some more fine control over programming operations.
Example Usage
- Identify the chip you are programming and set the DIP switches accordingly
- Settings can be found in Fujitsu documentation. The /CS and RTS switches should stay ON.
- Connect the USB-RS232C port to the assembled MB9X-UART PCB
- extension of the USB cord is preferable to extending the RS232-C connection. in other words, connect the MB9X-UART directly to your adapter.
- Connect the MB9X-UART to your target board, and turn on the power
- Invoke the ISP-MB9X program from the command-line.
- For example:
isp-mb9x.exe /1 /o4 /MB90F553A /b ROM /ruses serial port COM1 to dump the ROM from a Fujitsu MB90F553A running at 4MHz into a file called ROM.- Caution: running the program without the /r command will erase the ROM from your MCU by default, so be careful!!
- you must add the .mhx file extension manually as the isp-mb9x program will crash if you supply a file extension in the command line.
- For example:
- Wait for the read to complete being careful not to disturb the cables.
- Power off your equipment and unplug the board

Questions
How big is the MB9X UART PCB?
It measures 36.4 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MB9X UART use?
15 parts, built around the MAX232ID and BAT85. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MB9X UART KiCad files?
From the famicomical/MB9X-UART repository on GitHub, at the commit this page was made from: the board is MB9X-UART.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MB9X UART design in my own project?
Its repository states no licence, so its author keeps all rights: ask famicomical before reusing the design.
