Great compact solution
For Dynamixel Interface
Neat solution in a very compact form and the board can be used for different types of dynamixel motors with different motor voltage, different motor TTL voltage and different mcu logic voltage. All the level shifting are done on board and all the different power pins are exposed. The Arduino library is written in a user friendly way and supports old and new dynamixel protocols.
Lastly, the communication with the seller is amazing every time. Upon my request he added more example codes. I am pretty new to Dynamixel and amature at best in Arduino coding. But the seller made everything easy for me, we had a lot of discussion in email.
Although, the shipping took a little long, I did not mind supporting this seller and his work again and again.
