The issue with the MDP-M905 is that it doesn't work with USB-C chargers, only USB-A. This article describes a way to enable this missing functionality through good old-fashioned hardware hacking. -The MDP-M905 has a USB-C connection for power, alongside a classic barrel jack. However, the USB-C port is not wired properly according to the USB-C specification. USB-C is more complex than older connectors; it requires an exchange of information between the connected devices before providing power. The issue lies in the absence of a crucial component: two resistors on pins A5 and B5, which need to be pulled to ground through 5.1kΩ resistors. These pins, known as the "CC lines," are responsible for enabling USB-C to USB-C charging. +The MDP-M905 has a USB-C connection for power, alongside a classic barrel jack.

These pins, known as the "CC lines," are responsible for enabling USB-C to USB-C charging. Notice the two resistors R5 and R6 in the example above. Fortunately, the fix is simple: attack the board with a soldering iron and a steady hand to add the missing resistors. diff --git a/content/posts/enabling-usb-c-chargers-on-miniware-mdp-m905/usb-c-pinout.png b/content/posts/enabling-usb-c-chargers-on-miniware-mdp-m905/usb-c-pinout.png new file mode 100644 index 0000000..832d1f2 Binary files /dev/null and b/content/posts/enabling-usb-c-chargers-on-miniware-mdp-m905/usb-c-pinout.png differ
