Hello, 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 to increase PWM to 16 pins ( www.adafruit.com/.../815) L9110 to drive the motors at a speed depending on the PWM ( me.web2.ncut.edu.tw/.../L9110_2_CHANNEL_MOTOR_DRIVER.pdf) I plan to remove the breakout boards of all the chips when I do start manufacturing. Please let me know your thoughts on this setup or let me know how I can improve it with different components.

Adding PWM pins NRF51822 for Production

Hello,

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 to increase PWM to 16 pins (www.adafruit.com/.../815)
L9110 to drive the motors at a speed depending on the PWM (me.web2.ncut.edu.tw/.../L9110_2_CHANNEL_MOTOR_DRIVER.pdf)

I plan to remove the breakout boards of all the chips when I do start manufacturing.

Please let me know your thoughts on this setup or let me know how I can improve it with different components.
