Free release - ESP32 OSR2
Added 2025-03-05 00:34:33 +0000 UTCHi Guys,
It's time for a free release. I'm making available a version of the OSR2 - based on the ESP32 - along with a dedicated set of build plans.
I'm doing this because I have been working with the guys over at Haptics Connect and I'd like to promote some of their work. They have come up with their own firmware for OSR2, which can be loaded onto the device using an easy web-based tool. It's pretty cool and a neat way to get an OSR2 working quickly and easily. It's also able to connect to Haptics Connect web-based content.
This particular version of the OSR2 is based around a voltage regulator and a USB-C trigger module, which makes it possible to power the OSR2 using a laptop power supply. Other types of power supply for the servos can be used of course.
As with all OSR2s this is of course compatible with the OSR2 pitch module, which is also available for free on Thingiverse, and supported by the Haptics Connect firmware.
Have fun!

They are on a display stand I used for photography. My devices are all designed around a VESA 100 mount though and I also included mounting holes for a RAM mount on OSR2.

2025-10-04 12:47:05 +0000 UTCThis firmware bricked my osr2+ is there any way to completely reset the osr2? Or re flash it? I don’t really know the terms sorry any help would be super awesome though because the device was working nicely for me before installing this
Hi Hello
2025-05-27 02:17:40 +0000 UTCHere's what I expect ESP32 provides a rectangular signal to the servo, so connect the line from esp32 to one of the ALL servo lines The left servo is D15 on the ESP32 The right servo is also D13 The twist servo is D27, and the pitch servo is D4 You need to check the servo pin assignments Split the 8.4v power supply positive in parallel and connect it to the positive pins of all servos Connect the 8.4v power supply GND to the servo GND pin and one of the ESP32 GNDs Finally, connect the USBC to the PC Is this correct?

2025-03-27 08:30:29 +0000 UTCBoards that use 20v are hard to come by and not cheap. I think it would be cheaper to buy an adapter. Where can I find simple wiring instructions to power the ds3235 directly with 8.4v from an external source and use the ESP32? This is my first time using the ESP32, so I'm not confident.
