Ardu2040M | An Arduino style RP2040 RGB Matrix board

[tltangliang]

A new product from wisdpi - An Arduino-like Development Board with RP2040 MCU and WS2812 Matrix.



Features:
- Arduino Shield compatible
- BOOTSEL and RESET key
- 5x5 RGB Matrix
- Wide voltage input
- DC power jack
- Exposes all rp2040 GPIOs
- 3-pin SWD header

Specifications:
- DC jack input voltage: 7~15V
- Dimensions: 68.6x53.3x11.6 mm
- Weight: 18 g

USB:
- Vendor ID: 0x2E8A
- Product ID: 0x1067 (Distributed by the Raspberry Pi Foundation)

Compatibility:
- Only support 3.3V IO shield

I found that they got a USB PID distributed by the Raspberry Pi Foundation. That's cool.

I have checked their wiki and store. Well-documented and fairly priced.

AMS1117 when powered from 15V (max input voltage shown in the specs) produces 3.3V and needs to drop ~12V.
RGB LED event at 3.3V needs maybe 20-40mA? Say 30mA at full brightness. It gives 25*30mA ~0.75A
And dissipated/lost power (AMS1117) of 0.75A * 12V=9W.

Of course nobody will use the board at extreme condition...
