Top 5 Positive Customer Reviews for diy キット
VERY small circuit, ideal for hiding inside model railway decor to trigger accessories as the train passes. It will need a small relay to do this, as the circuit runs on 3VDC, and low current. But it will be fun! Many thanks!
Nice item, the second one for me. Unfortunately, I faced with D19-D27 not blinking issue on A board. Hope the issue can be in capacitor or transistor defect. The rest functionality works fine: Speaker sounds nice, the item can read SDcard at least of 16GB volume and USB Flash drive 32GB.
