* Powering via 5V USB is recommended. | |||
* Voltage on GPIO47 and GPIO48 is only 1.8 (V<sub>SPI</sub>), unlike the other pins (3.3, V<sub>DD</sub>). | * Voltage on GPIO47 and GPIO48 is only 1.8 (V<sub>SPI</sub>), unlike the other pins (3.3, V<sub>DD</sub>). | ||
* There are no default I<sup>2</sup>C pins. All GPIOs can be used with either of the two controllers with no penalty. | * There are no default I<sup>2</sup>C pins. All GPIOs can be used with either of the two controllers with no penalty. | ||
* Some devkits require the two RGB pads to be shorted before their WS2812 RGB LED can be used | |||
** I suspect this is because the WS2812 can damage the eyes if looked at directly? Unsure. | |||
** Version 1.0 of the DevKitC had the WS2812 on IO48; Version 1.1 has it on IO38. | |||
