The PSoC4 needs between 1.8 and 5V. So it will run directly from e.g. a LiIon battery or 2 (or 3) AA cells. For anything else you will need a voltage regulator.
Assuming that you are using the Pioneer kit, you need to connect the battery to the GND and V3.3_EXT pins (on the J1 header these are Pins 2 and 5 respectively). The Pioneer kit has a voltage regulator on board (on J1, Pin 1), which can handle 5-12V (see page 33 in the Pioneer kit user guide).
You mean, want to use external power supply
You can connect a battery to Vin, J11, 2pin header
voltage is 6V to 12V is better
Oh! Do Not Connect a battery to V3.3_EXT pin
This is the Voltage Output pin for V3.3 devices
One can use V3.3_EXT to supply power to the PSoC board. The onboard LDO is pretected against reverse currents. But J9 needs to be set properly for that (to 3.3V, not Vbus).
Can you run Psoc 4 Off battery between 6v-12v and program it via usb at the same time? silly question but i dont want to burn my board
From the Pioneer user guide -
The onboard programmer supports only the RESET programming mode. When using the onboard
programmer, the board can either be powered by the USB (VBUS) or by an external source like an
Arduino shield. If the board is already powered from another source, plugging in the USB
programmer does not damage the board.
I dont know if it makes a diffrenece but can i use a 2200mah 3 cell li-po battery ? Voltage on it is 12.6v fully charged. Its usually use for RC purposes.
J11 is for an external power supply pin, It has a voltage regulator inside.
Its allow 5 to 12v, I think 12.6v is in tolerant
Whatever kind of battery will work,
Just taking precaution before i put the battery on. What does this mean in the datasheet?3.3 V (Vin= 5.3 V, Iout= 10 mA, TA= 25°C) (Vin= 4.75 V to 10 V, Iout= 0 mA to 800 mA) (Note 4)5.0 V (Vin= 7.0 V, Iout= 10 mA, TA= 25°C)(Vin= 6.5 V to 12 V, Iout= 0 mA to 800 mA) (Note 4)LDO datasheet link:http://www.onsemi.com/pub_link/Collateral/NCP1117-D.PDFI think it mean if i hook up 12v it will regulate down to 5v not 3.3v.Thank you for you input everyone.
The regulator will take 20V, but you need to compute worst case Pdiss
to establish the regulator can handle the rise in Tj for the power you
J9 is change VDD voltage to 3.3V or 5.0v but voltage regulator is adjusted to 3.3v
When you use battery for power supply to J11, VDD is just only 3.3v
If you want to use VDD as 5.0v you have to use power source from VBUS of USB.
On other hand, the regulator's voltage is adjust by R35, R36
so, if you want to use 5.0v with battery power source anyway
You have to modify the resister R35, R36 ratio.
The board can also be powered with an external power supply through the VIN (J11) header; the allowed voltage range for the VIN is 5 V to 12 V. The LDO regulator regulates the VIN down to 3.3 V.
so to be safe i should probably connect 5v not 12v to pin J11?
No problem, of course.
