It's a small size (5x10mm) linear constant current source for LEDs. Supports pulse-width modulated (PWM) by a microcontroller for LED dimming. Selectable current 10-20mA via SMD jumper (default 10mA).
There are two options.
BCR421U - Assembled PCB:
BCR421U - White LED, Breadboard (Assembled):
BCR421U - White LED, 15cm Cable (Assembled):
BCR420U - Assembled PCB:
Maximum power dissipation (Pd) 0.2W (25°C)! It has no officially polarity reversal protection
Example of calculation BCR421U:
Example of calculation BCR420U:
Never underestimate electrostatic discharge (ESD)! The return does not apply to mechanical damage. If you exceed the maximum power dissipation 0.2W, voltage and driver burns, there is no return or refund.

Due to COVID-19, the delivery of international shipments to some countries is extremely slow. I don't have a chance to speed it up. Also, sending your shipments will take several days due to the "General Lockdown" in my country. Also, shipments to some countries are suspended. This list is constantly being updated, so it is difficult for me to keep an up-to-date list of allowed countries. If you create an order and it is not possible to send the shipment to your country, you will receive a full refund.

Therefore, I set a period of 90 days for refund. If you are unable to wait or do not agree with the delivery time, please do not create new orders. It is not my fault but "force majeure" :(
