Raspberry Pi用16チャンネルサーボコントローラHATキット

Got this product just recently, it worked perfectly! No issues whatsoever! Price is reasonable. A great alternative for BotBoarduino Shield, which is costs twice as much.

Easy to put together and works well (even after I hooked power up backwards)

Works great for my robot and the Raspberry Pi

Great little unit. I had never soldered before and mine turned out great. The only downside side is having to solder all of your own headers (if you're a newbie like I was)

Easy to use, works really well. I wish I had of noticed it does not come with the extended headers so you can stack other boards on top. Also note when exiting Python code using this device you need to terminate the output otherwise the servos are powered and receiving a PWM signal until you reboot the device.
