Product Details
Description:
1: Double-sided wiring, the pads are sprayed with tin and the pads processed by the tin process are enlarged, which can withstand repeated desoldering and is not easy to fall off;
2: Self-variable bending is not easy to occur (refers to bending caused by non-manual conditions), and poor sheets will bend with time and environmental changes
3: Impedance is more stable and reliable
4: Improve DIY fun
5: Simple to use

【1】Function description
After pressing the start button, the lights corresponding to numbers 0-9 will light up randomly at an interval of 0.5 seconds. Observe and remember the order of the lights. After all 10 lights are on, the device will start timing. At this time, you can press the recorded lights. Press the corresponding buttons in sequence to turn off the lights.
When all 10 lights are off, the answering is over, and the device will display the answering time and the number of correct answers. 1 point for each correct answer, for a total of 10 points. The higher the score, the better the memory. Memory skills can also be exercised with frequent such tests.
For example, the lighting sequence is 0123456789, and the button lighting sequence is 0123456798, so the score is 8 points.

Front picture of the empty board of the circuit board (different batches, colors will be different, please understand):
The circuit board is made of FR-4 military grade A material. The tolerance of the sheet and the stability of some parameters, the A material is very strong, which is beneficial to the price compared to other sheets. PCB board
The back picture of the empty board of the circuit board:
The parameters of the components are directly printed, and it can be directly soldered without referring to the circuit diagram, which is quite convenient.
