16 Channel PWM Servo Motor Driver Controller Board Module Bluetooth PCB steering gear for SG90 MG995 Arduino Robot Raspberry Pi DIY Servo Shield Module

After initial frustration due to lack of documentation and details I took the time to read their manual and try it out and it works just like its supposed to!it is actually very easy to use and I love it. Much potential for cool development. On my windows 10 machine I did not even need ftdi drivers it just works of the USB port.

The product good run the servo Motors but the app did not want to work correctly would not save any work would not recommend this product to anyone the Wi-Fi cables were not in the correct order so had to figure out which ones to get them to work

The seller has posted PDF documentation and software links in the Q&A area, these are requited to get this running.I'm giving it 4 stars because it works as described but took a little while to figure out. (only tested over USB though, no idea about ttl, or the optional Bluetooth attachment). Also note USB alone will not power the servos, you need to attach an external 5v power supply.(However!)This uses an STM32 F103C8T6 (CPU) . There are some Arduino libraries written for STM32, and was hoping I could program it directly, I have not had much luck yet. I think I have to use TLL and burn a new bootloader or something idk, I'm a noob.

This device does not have and software available online or anywhere else. Hard to tell if I have received a defective unit without the app shown in the documentation to test with. Would not recommend this manufacturer or this product.
