2.3 Powering the board
The board is powered either via the PWR jack or via a battery. It should be supplied from a 6V to
16V source with maximum current of 1A from the power jack.
All measures below are taken at 10V.
If measuring the current consumption it should be around 0.06A before initializing all the
peripherals. The consumption raises to 0.12A without WIFI and USB hosts initialized and Linux
running. The consumption goes up 0.15A with the Linux running when WIFI and both USB hosts
initialized.
If you have a standard USB flash drive attached to a USB host, Linux and WIFI running the typical
consumption is around 0.20A.
When powered by the typical 3.7V battery the WIFI and USB-hosts will be disabled if you use
external 3.3 DC-DC (not mounted by default).
For the European customers we sell a power supply adapter 12V/0.5A –
SY0612E.
2.4 Prebuilt software
Note that the boards arrive without Linux or SD card. The Linux image can be purchased
separately on a SD card or you can built and write it yourself.
When we program the boards we change the default position of the following HW_OCOTP_ROM0
fuses of the processor:
SD_MBR_BOOT(3) - Blown
SD_POWER_GATE_GPIO(21:20) – 10-PWM3
For burning the fuse position we use the BitBurner software. This operation is discussed in details
before. Proceed with great caution when burning fuses since it is irreversible operation.
