I use a big development board for prototyping but for the final product I like the compact size of this module. Every device I have used has been very well made and totally reliable. Battery connectors are a welcome addition. I don't need the many solder and wire wrap connectors that come with the kit, but it's VERY nice to have them just in case. I have used many HiLetGo modules over the past year and have never had a problem. highlighted.
