====== Didj-Fi Cartridges ======

The Didj-Fi (pronounced digi-fi) is a set of cartridges with WiFi for Leapfrog devices. The design is open hardware and open source. You can find [[https://github.com/jkent/Didj-Fi|the source repository here]].

==== Didj-Fi =====
{{ :devices:pollux:didj-fi_pcb_front.png?250|}}

  * ESP-12F module
  * CH340E USB UART
  * USB Micro B connector
  * 3-position switch for boot mode

Boot mode switch:

^Direction        ^mode          ^
|Counter-clockwise|UART          |
|Center           |Device default|
|Clockwise        |None (RAM)    |

**Note**: For the Leapster Explorer and LeapPad Explorer 1 you must [[devices:pollux:boot_modification|make some modifications]] to the device for UART boot to work.

==== Didj-Fi NAND =====
{{ :devices:pollux:didj-fi_nand_pcb_front.png?250|}}

  * ESP-12F module
  * Large block NAND
  * 4-pin serial header
  * Solder jumpers for boot mode

**Note**: The v1.0 silkscreen table is backwards in regards to the Cartridge and Internal NAND boot options. Please use the below table.

Boot mode solder jumpers:

^SD[7]^SD[6]^SD[5]^Boot mode     ^
|  X  |  X  |  X  |Device default|
|  X  |  0  |  0  |UART          |
|  0  |  0  |  1  |Cartridge NAND|
|  1  |  0  |  1  |Internal NAND |
|  X  |  1  |  1  |None (RAM)    |

**Note**: For the Leapster Explorer and LeapPad Explorer 1 you must [[devices:pollux:boot_modification|make some modifications]] to the device for UART and NAND boot modes to work.
