Got some new components for the LiDAR today.
TX Qi-modules.
a couple of Mini VESC´S that I will evaluate with encoder and FOC mode.
I am also wating for a L6234D BLDC driver which should work quite nice with the PM2805 BLDC motor.

LIDAR-Lite V3 serial communication with IrDA2 Click and two NodeMcu’s at 115.2kbit/s
Neat! Any surprises when working with those?
@scharette Yes in fact it was. Took me a while to understand that RX is TX and TX is RX on the board. Rather then that they worked fine. 
Hehe… it is often the simplest things that cause hurdles! 
Good to know they are easy to work with. Have you had a chance to try longer distances, etc.?
Sure I can give them a test on longer distance. I think 1meter is the limit on 115.2kbit/s. Since one need to solder the baudrate selection I will only test 115.2kbit/s. From the start baudrate is 9.6kbit/s
So time for a small update on this project.
We have a the first prototype ready for testing (1-axis rotation with IR and Wireless power).
We made it bigger so we could fit all kinds of pre-built components within.
We are using the IrDA2 click board for IR send / receive LidarliteV3 data between the Nodemcu´s.
First test is partly successful. While utilizing the USB on both Nodemcu´s the IR transfer is successful with 115.2kbit/s and data is returned successful.
If we try to power up the Nodemcu (the one that is placed inside the lidar head) and utilizing the power coils the serial mointor for the the other Nodemcu freezes (The one that is outside and connected over USB and should receive the IR data from the head.
Maybe there is some interference from the Wireless power coils that destroys / interference with the TX/RX lines on the IrDA2 board communication. I would also need to check if the power is sufficient from the RX power coil.
Previous tests with simpler solutions worked without any problem when running over wireless coils.
Here is a very simple sketch on how it’s connected:
Any suggestions? Please feel free to to leave a comment
So last night I was testing to use ESP-NOW to transfer data between the two Nodemcu´s. We are still using Wireless power for the rotating head, the ESP-Now does not seem to get any interference from the Coils (As the IrDA2 boards) which is promising.
For a first test this seems promising, I need to improve speed and see how fast we can transfer data over ESP-Now.
Wow! That is very promising indeed!
Tonight I have been working on some speed improvements for data transfer over ESP-Now. It’s a improvement! 
Did you have finiched your project?
