Product description

Colour:9 Pack

UCEC 9 Pack 3.3V/5V Power Supply Module provides dual 5 V and 3.3 V power rails, and has a multi-purpose female USB socket, can plugs directly into a solderless breadboard.

Features:
1.Apply to MB102 breadboard.
2.Two ports of power output. You can switch the power voltage of both ports between 3.3V and 5V by the jumper cap.
3.There is a green LED to indicate the presence of power, and an ON / OFF latching switch to control the power to the board.

Specifications:
- Locking ON / OFF Switch
- LED Power Indicator
- Input Voltage: 6.5 V to 12 V (DC)
- Output Voltage: 3.3 V / 5 V DC
- Maximum Output Current: 700 mA
- Power Rails 0 V, 3.3 V, 5 V on Breadboard
- Two Groups of Header Pins
- Size: 5.3 cm × 3.5 cm

Note:
1.12V is the voltage limit. If you use an AD-DC adapter, you're recommended to use 9V in case of unsteady voltage which may burn the board.
2.Be sure to orient the module correctly on the breadboard so that power lines up with the red stripes. It is easy to mount it on the wrong end.
3.Do not connect both a DC power plug and powered USB at the same time or damage may result.
4. You can buy an AC-DC adapter with a 5.5mm/2.1mm plug and 9V or 12V power supply.
5. The module input is 6.5V-12V. If the input 5V is not 5V, the input and output of the voltage regulator chip will have a voltage difference, otherwise it will not work.

Package Includes:
9 x UCEC MB102 3.3V/5V Power Supply Module

5.0 out of 5 stars Great hobby supply -
Reviewed in the United States on 4 March 2018
Received 6 units on time and in good condition. The boards must be carefully snapped apart. (a minor inconvenience considering the price)
With an 8.2V battery supply input, they demonstrated 1-2mV AC ripple. The 5V sections averaged slightly below 5V at 4.98V (no load) which dropped to about 4.87V under 500mA load.
3v sections were at about 3.24V. The pushbutton power switch must be slightly pulled back when pushed to lock into position. (not super intuitive)
For simple hobby projects this is a great deal. Super convenient! The seller emailed me to make sure the units were received in good condition. A nice touch and certainly unexpected for such a low price order.
The following 9V plug adapters would be a good fit with this: [[ASIN:B018WWI39W [2-Pack] 9V 1A Power Adapter for Arduino[UL/FCC Certified],AC DC 9V 1A 1000mAh 100V-240V Converter Adapter Power Supply 5.5/2.1mm Plug US; 160CM Cable]]
Google UCEC MB102 pdf to find cut sheets and schematics for this unit.
Solid product at a great price.

4 of 6 received were unusable. Pins were soldered at such bad angles they wouldn't work on breadboard.
