- In this video I go over the steps required to use the Servo2040 board to build my hexapod.

Definitely a good choice on the servo2040. I have been very tempted by them myself. 18 servo channels and 6 analogue inputs and a built in current sensor (albeit for all the servos at once)? Perfect for a hexapod. I’m seriously considering buying one now. Only problem is that if I want to add position feedback or individual servo current sensing then it wouldn’t be suitable and I would have to make my own board anyway, I might go for an FPGA based solution eventually. I would need some other controller anyway since the servo2040 doesn’t have many pins left for sensors.
yeah I think they had the hexapod application in their mind when designing the sevro2040. Yes that is one limitation of this board and the only extension is via its I2C pins. But for the price it is a pretty good deal. you should be able to find it for ~$24 online, which honestly is really good for what it is.
Printing one right now.😀
It is a pity that Pimoroni Servo2040 is not sold in Russia, we will have to use another one. But the main thing is that you have already created a basis, and adapt other boards, I think, will work. I took the LX-225 servos from HIWONDER, they have two modes as servos and motors and can be connected in series. And I took a 1.3 mm binocular USB camera module.
yes, as you said, for example you can use a RP Pico or an Arduino to receive the open hexapod protocol from the phone and send serial commands to LX-225. I think it should work too.
please can MG996R servo motor work for this project
You are the best!!!!!!!!! 👍👍👍👍👍👍👍
I want one 🙏🙏🙏🙏🙏🙏🙏🙏🙏
Awesome work!
Cool cool cool ! :) 2040 ordered ! ^^
This is amazing
Hello where do you learn kinematics /inverse kinematics to make this type of robot??
I did the calculations myself. but definitely ask in the discord server to get more detailed answers.
I just purchased the servo2040, a nice board and much smaller than I thought it would be. thanks for suggesting. I was wondering what is the purpose of the relay switch?
The relay controls the power to the servos, so it allows the microcontroller and therefore phone too, to cut the power to the servos.
Amazing video, I am considering of doing the same thing, but with MG996R servos. I have a couple of questions in mind:
1) the max constant current for the servo2040 is 10A (read it on the datasheet), don't you exceed that with 18 digital servos?
2) Is it possible to control the servo2040 without a phone and use Bluetooth, wifi, pwm signals, etc?
3) the mg996R that I plan on using is operational with voltage within 4.8 V and 7.2 V, could I use a 7.4 lipo battery directly or should I search for an UBEC?
Thanks in advance, keep up the great work, sorry for posting the questions here, not sure if this is the best way to reach you
Nevermind, I am stupid, just found about chipo
can someone explain the need of relay switch?
How i cut the thing in the back?
Its contrlled by the cell phone?
Yes, and the remote control is a phone too. See my other videos on that.
I have question, how to expand the 18ch? Any clue?
you can't do that directly on this board. But you may be able to use a second board (this or other pwm board) and chain it via the I2C pins
Hello to all! Did anyone know if servo2040 could be drive by Raspberry pi? 😊
does this work on I phone?
no iphone support yet. only works on android phones.
Hi all can anyone advice me on servo2040, i try to drag and drop firmware and the drive automatically off line after i droped the file and ever rebooted. have try mant time dont works....
I think you have found the answer to your question by now, but if not, definitely ask on the Discord server.
Pimoroni Servo2040 is not sold in Viet Nam. It is very sad
:(
that's a lot of pwm ports
18 of them. designed for a hexapod probably!
Servo2040 is not sold in China. It is so pity.
aww sorry about that. but how do you have access to CZcams in China?
