https://devzone.nordicsemi.com/f/nordic-q-a/38308/high-drive-capabilityHi, I&#39;m developing a product with the NRF52832. I have one Blue LED (APA2107LVBC) which is driven directly by a GPIO as shown below : With a typical Vf of 2.65V, the current should be limited to 4.3mA. My GPIO is configured in High Drive H0D1en-USTelligent Community 13Sun, 09 Sep 2018 16:48:52 GMThttps://devzone.nordicsemi.com/thread/147901?ContentTypeID=1Sun, 09 Sep 2018 16:48:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:138f7864-71e8-4e03-81b0-937b7eb1a7f6julienh<p>That works.

Polarity is OK, since it lights up when you connect it to GND.</p> <p>Which GPIO are you using for this (&quot;LED_1&quot;)?</p> <p></p> <p>Best regards,</p> <p>Håkon</p><div style="clear:both;"></div>
