Any TR8303C can run the V4 code. Fact: Clone or counterfeit TR8303C modules often use cheaper ADCs that cannot achieve true 14-bit stability. If your unit cost less than $15, the V4 code may actually perform worse due to amplified noise. Always buy from authorized distributors. In the world of precision control, better resolution
