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.

The primary interface to the target device is a 40 pin ZIF (zero insertion force) socket. Digital IO at LVCMOS3.3 levels is supported direct to the MCU on every pin. Inputs above +3.3V will be clamped. The VDD bus can be switched to pins 1-16 and 25-40. The VPP bus can be switched to pins 1-10 and 30-40. The ground bus can be switched to pins 1-16, 20, 21, and 25-40.

Photos of a TL866 II PLUS bought April 2018 from eBay seller goldenchipset.
Red and yellow LEDs were desoldered from mainboard to allow separation of the two PCBs.
