The TL866 II PLUS is NOT compatible with the TL866 A / TL866 CS models. The microcontroller has been changed from a PIC18 to a PIC24F and there are other significant schematic changes. The plastic enclosure for the TL866 II PLUS is identical to the TL866A / TL866CS.

Hardware

The TL866II PLUS is driven by a Microchip PIC24FJ256GB110 microcontroller which connects directly to the USB.

Red and yellow LEDs were desoldered from mainboard to allow separation of the two PCBs.
