QRCode2 is hot
-
Hi, I’m using the AtomS3 Lite with the QRCode2 Base.
The QRCode2 draws a high current of around 170 mA at 5 V and starts to heat up after a few minutes, even in pulse mode.Is this normal?
Is there any way to reduce its power consumption?Tomas

The Atomic QRCode2 Base (SKU: A133-B) typically draws a working current of around 174.18 mA at 5V when connected to an Atom-Lite. Your observation of 170 mA is within the expected range, so this behavior is normal.
However, if the device is heating up significantly, you can try the following to reduce power consumption:Use Pulse Mode: Ensure you are using the TRIGGER_MODE_PULSE mode to minimize continuous power draw.
Adjust Lighting: Reduce the brightness of the fill light (set_fill_light_brightness) or turn it off when not needed (FILL_LIGHT_OFF).
Limit Continuous Operation: Avoid prolonged continuous scanning by using shorter decode delays (set_decode_delay).If the issue persists, check for firmware updates or ensure proper ventilation around the device.
