This is expected behavior. The module's current detection range is 50mA–10A. Although the effective current shows a value, the energy consumption does not increase. You can verify if no device is connected by checking the first byte of raw data; if it is `0xF2`, no load is connected.

87

88
+The 10A and 20A ratings refer to the maximum current the module can measure. The difference between the modules lies in the current sampling resistor; everything else is the same.
89
+
90
+- The 10A version uses a 0.003Ω (3mΩ) sampling resistor, and its current coefficient is 0.333.
91
+- The 20A version uses a 0.001Ω (1mΩ) sampling resistor, and its current coefficient is 1.
92
+
93
+The chip in the 20A module can actually measure currents up to 30A, but the module itself is too small to safely handle such high currents. Regardless of whether you are using the 10A or 20A version, it is recommended to reinforce the 220V traces with additional solder.

+**Input & Output**: As clearly indicated in the datasheet, you can use the module well if you have a >300mA input dc supply in 4.5-5.5V range but the maximum output load current never exceeds the 200mA at 5VDC limit.
40
+
41
+**Inside Circuitry**: Although I didn’t get a worthy chance to break apart the B0505S-1W module, it came to my notice that its inside electronics is mainly based on the “Royer Oscillator” (https://en.wikipedia.org/wiki/Royer_oscillator) circuit.
42
+
43
+As far as I know, the traditional Royer oscillator circuit only provides basic functions but once the circuit is abnormal, the module may be damaged and even cause serious consequences. **At present, the module is available without a continuous short circuit protection (SCP) feature!**

56
+Gen-1: Basic HUB75 panels using 4–5 address lines, simple driver chips (ICN2037BP, FM6124), and separate row decoder chips (like 74HC138 or FM6124A). These panels are compatible with the Adafruit MatrixPortal S3, RP2040, and Adafruit libraries.
57
+
58
+Gen-2: Panels with smart driver chips (like ICND2038S or ICND2153) that handle internal row multiplexing and require initialization sequences. These may use fewer address lines and are not compatible with most simple microcontroller libraries without modifications. There are some great libraries on Github that provide control of these panels using an Raspberry Pi controller.
59
+
60
+Gen-3: Advanced grayscale panels using chips like MBI5153 or ICND2153 that support PWM or stacked PWM (S-PWM) for high refresh rates and deep color. These require precise signal timing and are typically driven with FPGAs or heavily modified firmware. Some GitHub projects have figured out how to support these.
