Revision 1.00 has been tested for assemblability and potential wiring problems, supports power supply via pico and a 5.5 mm x 2.1 mm DC-005 round connector (plus in the center) with a supply voltage of 5-12 volts passing through the voltage stabilizer L7805ABD2T-TR
The Bill of Materials contains resistors for HDMI, for VGA, the following resistor nominals are required: R4 = 820R R5 = 360R R6 = 820R R7 = 360R R8 = 820R R9 = 360R R10 = 75R R11 = 75R
The jp5 jumper needs to be soldered if an additional PsRam RAM chip is installed
The jp4 jumper does not need to be soldered if the AMS1117 3.3 stabilizer is planned to be installed. If it is soldered, the stabilizer built into the Rpi will be used
Revision 1.02 uses a pulsed step-down voltage regulator LM2596S-5.0, 5V 3A 150kHz [TO-263-5.] to lower the power supply, but this revision has not yet been tested for assemblability.
