Translating step 15

Step 15
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:
  • 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 TI 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.

之前提到过的标记得很好地主板,由超过一打的接触点和关键控制硬件。

不同于我们在开发者版第二版中发现的ST微电子LED驱动, 这个 IC 序列来自于德州仪器:

3个TI TLC59401 16频 LED 驱动,带有点校正和PMW灰度控制。

在背面,我们看见一对相对来说大一些的电容器——可能会使巨大的红外LED灯阵列发出的间歇性脉冲更为平顺。
