https://devzone.nordicsemi.com/f/nordic-q-a/17025/adding-pwm-pins-nrf51822-for-productionHello, I am thinking of creating a project that I intend to manufacture that needs to operate 10 dc motors via Bluetooth. Would this be a logical and cost effective setup: NRF51822 as a Bluetooth transceiver and processor PCA9685 chip toen-USTelligent Community 13Thu, 13 Oct 2016 13:44:52 GMThttps://devzone.nordicsemi.com/thread/65309?ContentTypeID=1Thu, 13 Oct 2016 13:44:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:713f70f4-9a77-44b8-b5c4-580db8a2c2bdJ&#248;rgen Holmefjord<p>Hi,</p> <p>Have you considered using the nRF52832, which <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/pwm.html?cp=2_2_0_46#concept_pzc_1pw_nr">support up to 12 PWM channels</a>?</p> <p>In our SDK you can find an <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.0.0/pwm_hw_example.html?cp=4_0_0_4_5_18">example</a> of using the PWM driver. Here is a <a href="https://devzone.nordicsemi.com/blogs/941/hexapod-using-nrf52-dk-part-1-intro-and-hardware/">blog post</a> on a design where the nRF52-DK is used to control up to 20 servos using HW and SW PWM. Unfortunately, the post about the software part is not yet published.</p> <p>Good luck!</p> <p>Jørgen</p><div style="clear:both;"></div>
