rh1tech board for Fastbeta
Mikhail rh1tech has developed a board that is fully compatible with the Fastbeta firmware
  • 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.
Made on
