Version Information
Version 1.2A
Version 1.2A is the most recent development version of the SpoolScale. It is functionally identical to Version 1.2, but with optimizations made to allow for mass production using mid-scale manufacturing maker resources in the United States.
- Reduced part variety where possible
- Removed fine-pitch VQFN microcontroller, replaced with pin-compatible SOIC-300 (VQFN footprint retained as a backup in case of chip shortages
- Replaced resistor nets with 0603 discrete resistors
- Placed programming test points for semi-automatic code uploading
- Optimized arrangement and positioning of components
Version 1.2
Version 1.2 was developed to correct a number of defects found in Version 1.1, as well as to incorporate improvements based on feedback from test users.
