  • The aforementioned well-labeled board, complete with over a dozen test points and the essential control hardware.

  • Unlike the STMicroelectronics LED drivers we found in the Development Kit 2, this IC array hails from Texas Instruments:

  • 3x Texas Instruments TLC59401 16-Channel LED Driver with Dot Correction and Grayscale PWM Control

  • On the reverse, we see a pair of (relatively) large capacitors—probably necessary to smooth the intermittent load of pulsing such a huge array of IR LEDs.

上述标记良好的主板，由超过一打的接触点和关键控制硬件组成。

不同于我们在 开发者版第二版 中发现的意法半导体的 LED 驱动, 这个集成电路阵列来自于德州仪器：

3个德州仪器 TLC59401 16频 LED 驱动，带有点校正和 PMW 灰度控制。

在背面，我们看见一对（相对）较大的电容——可能用于发出更为平滑的脉冲间歇负载，如巨大的红外 LED 灯阵列。
