[http://megasquirtavr.sourceforge.net/manual/Basics.Install.Mechanic.html [Manual: Basics.Install.Mechanic]] Soldering steps reminder list. '''Before mintest''' * big black barrell inductivity (1.5uH 5.4A or blue 3.3uH 8.8A) * quartz 16MHz * main fuse wire * 0 Ohm resistor on the bottom (D45 for stepper?) * -- R154 under the atmega -- (factory populated since v3.3) * -- LCD supply capacitor (C89) 10uF -- (factory populated since v3.3) * -- Big Vbatt capacitor (C72) 10uF (min.25V) 1210 -- (factory populated since v3.3) * Big 18V 1.5kE18 troughole transient suppression diode (bottom of the board) (factory populated SMB on top since v3.3, needs checking ! ) * -- connect the GND bridge -- (not applied since v3.3) * pinheaders for the ISP * do the firmware things and checks (bin/mintest.sh, bin/prog.pl) '''Mintest possible''' at this point * ... * supply voltages * supply current * LCD test requires special connector (since no header) or a bit of experience '''Optional stuff below''' * -- 5V1 protecting zener for trigger1 D14 -- (factory populated since v3.3) * -- 5V1 protecting zener for trigger1 D27 -- (factory populated since v3.3) * configure trigger1 to VR (2 jumpers) * configure trigger2 to HALL (1 jumper) * trigger1 pullup resistor REMOVE (R55) * EC connectors * -- flyback diodes -- (factory populated since v3.3) * flyback airwire (EC36 pin23) * FETs * IGBT * additional brown GND5 airwire on bottom (EC36pin21,pin22) * additional brown GND5 airwire on top (EC36 pin5) * flyback testing: all inj. outputs toward the flyback rail '''airwires to EC18''' * knock * RS232 * MAP signal (if not onboard MAP) * hotmelt '''Stepper''' * stepper chip * stepper capacitor (C75) 1210 (min.25V), 10uF * stepper Vbatt wire in the place of D45 '''knock''' * 4 MHz * TPIC8101DW knock chip '''for LCD that likes -3V contrast''' * -- R112=2k4 -- (factory populated since v3.3) * -- take out the 1k towards GND -- (not populated in factory since v3.3) '''Final tests''' * many * pump- voltage * wbo2_pump_pw_zero * wbo2_nernstdc_target (0.45V between nernst and pump- when WBO2 activated with mde02 or RPM signal) * 64-1 stim-out signal (mstbemsp03) from stepperA (0x36) output, and checking proper operation of all 8 injector and ignition channels with connected LEDs. Requires wasted-spark 16 cyl config with 64-1 wheel ---- '''See also''' * GenBoard/Manual
