In January 2025, we have tested and release a newer version of PPSTrigger that not only cost less but also bring out these new update:

• Smaller
• GNDed mounting slot
• Better ESD and flyback protection
• USB2.0 D+ D- pass-through

You can get the new board on Tindie if you are in the US. We will soon port them over to Lectronz for EU/UK/Australia shipment.
