Most of the detail is in the video. Again, a big shout out to PCBWay for providing the prototypes free of charge. Below are some of the 3D renders.
Please leave comments here on my blog or on my youtube channel if you have suggestions.
The First Prototype
The Jeffrey 2.0
PLEASE NOTE: Through-hole support for the battery holder has been discontinued after receiving feedback from the community. Only surface-mounted battery holders will be supported moving forward.
The Jeffrey 2.0 has Physically Arrived 🙂
The Jeffrey 2.1
Minor improvements are completed on The Jeffrey 2.1. On the front I have changed the TP4056 footprint so that the two clusters of two-solder points are designed in such a way that they hold the pins in place for you while soldering. I found that sometimes it was difficult to solder these pins in place as they kept moving and didn’t fit in a breadboard. These newly placed through holes should make assembly a little easier.
On the back there are a few changes as well. The 230k resistor typo from the official iSpindel web page has been corrected to 220k. Previously there was a V formation and an additional elongated through-hole allowing two resistors to be added together to get to 230k but since that isn’t actually necessary it has been removed.
