Describe the BOE module fitted to the Amazon Fire HD 10 (2017), an MT8173 tablet, as a third NT51021 panel. The methodology for finding the part number for this glass is notable, since it was done by process of elimination. The vendor firmware chooses between a BOE and an Innolux module from two board ID straps. This means whatever the two are, they are mechanically and electrically interchangeable in the one chassis. An Innolux module pulled directly from one of these tablets was pictured with the part number "P101KDA-AB0" on the back, and that part is 216.576 x 135.36 mm active, 227.926 x 143 x 4.4 mm outline, 51-pin MIPI with four data lanes, a four-string WLED backlight and a 3.3 V supply. The BOE module therefore has to match those specifications. Searching through BOE's panel specifications, only two panels match these constraints: TV101WUM-NM0 and TV101WUM-NM1. In particular the number of pins and the dimensions were the greatest discriminators. Measured on the available board (BOE), the tablet's LCM flex is silkscreened 1 at one end and 51 at the other, and the area was measured as 216 x 135 mm, and its backlight regulator is configured for four LED strings, which matches the TV101WUM-NM0. Finally, a replacement part listing for the Amazon Fire HD 10 (2017) device also names the BOE TV101WUM-NM0. The NM1 was released later than the NM0, but is the same mechanical design and would take the same programming. Even though the part number was not physically read from the test unit, this module is absolutely not the boe,tv101wum-nx0, on the pin count alone.
