After removing the touchpad assembly from the controller, we immediately notice that the daughterboard is near-identical to the one found in the Steam Controller.

Just like before, the touchpad is driven by a Cirque 1CA027 companion MCU.

As with the Steam Controller, the PCB also features seven well-labeled test points that make it easy to directly interface with the board for testing.

Up next is the 3.85 V, 3.69 Whr, and 960 mAh Li-poly battery. After giving it a good looksee, we spot the model number B0PLH100, and a large QR code.

Unfortunately, scanning the QR code doesn't reveal a secret message, just the serial number: 3SMA2638404214.

Amazing! We've got that same combination on our luggage.
