Official Hardware Versions
FujiNet is designed with a custom SIO plug which is intended to connect directly into any Atari 8 Bit computer and also has a custom SIO receptacle on the back for connecting to other “real” Atari peripherals. The heart of FujiNet is an ESP32-WROVER module with 16MB Flash & 8MB PSRAM. There is a MicroSD socket on the right side for storing disk images, printer PDF files and configuration information (wifi credentials, disk drive config, etc). Three buttons are easily accessible on the top and serve the following functions:
- Button A (Left)
- Short press: disk swap
- Long press: enable/disable SIO2BT mode
- Button B (Middle left)
- Short press: print debug info to serial console
- Long press: Safe reset (unmounts SD card before reboot)
- Hold during power up to reset FujiNet config
- Hard Reset Button (Right)
Three LED’s on the front provide the following status:
- WHITE (Left): WiFi
- BLUE (Middle left): SIO2BT Mode
- ORANGE (Right): SIO Activity
On the left side there is an ON/OFF slide switch (Up is on, Down is off). The MicroUSB port above the power switch can be used to power the FujiNet, update it’s firmware and provide serial debug console output. FujiNet can also be powered directly from the Atari through the SIO connector without the need for MicroUSB.
The entire hardware design is open source and available in our github repo.
Changes from 1.0:
- Add line buffer to SIO DATAIN and DATAOUT so FujiNet works on 1088XEL machines with builtin SIO2PC
- Hard reset button moved to snap dome on front (optional)
- 3rd button added to another GPIO for safe reset
