Another breadboard power supply designed by Seeed Studio. it can directly takes power from DC wall wart and outputs a selectable 5V or 3.3V regulated voltage.
Compare to other breadboard power supply designs, this one provided mini-USB port like the seeeduino , you can toggle the switch and select your power source. (USB or dc jack).
With this board, you can send power to both power lane of the breadboard, and each side has a on/off switch.
Model: TOL123D3P

The warnings and wrong operations possible cause dangerous.
It is the schematic, the circuit about Eagle resource like .pdf should linked here in order to avoid memory exhausted.
| Specification | Conditions | Min | Typ | max | Unit |
|---|---|---|---|---|---|
| Input voltage | 5.0 | 6.5 | 12.0 | V | |
| Output Voltage | Channel 3.3V | 3.235 | 3.3 | 3.365 | V |
| Channel 5V: 10mA≤IOUT≤1A, 6.5V≤VIN ≤12V | 4.9000 | 5.0 | 5.100 | V | |
| Current Limit | VIN-VOUT=2V | 1.2 | 1.35 | A | |
| Ripple Rejection | f=120Hz, COUT=22μF Tantalum,VIN-VOUT=3V, IOUT=1A | 50 | 70 | dB | |
| Temperature Stability | 0.5 | % |
Now you may de-activate power by the two jumpers, or adjust the vertical switches to select different voltage. The horizontal switch is used to select JST 2 pin or mini USB cable as input.
