Assembly
Progress
What's been done so far:
- Soldered inductor and fuse link and crystal which was missing for knock
- Soldered pin headers for serial, keyboard and LCD
- Soldered both Econoseal connectors
- Soldered wires for supply and connecting GND and GND5 at the board, only for testing
- Made DSUB connectors for serial keyboard and LCD
- Knock and EGT chips are on board
- Initial testing; connecting and communicating with PC, keyboard/LCD communication, updating firmware through bootloader
Apart from a firmware incompatibility issue all is good so far.
Notes
serial number 303, sent out on 2005-07-09 (among the first 5 v3.3 - these had no R181 PNP-ed)
- apparently you assembled yourself: confirm R181 has been soldered (100 .. 180k) according to the note you received from the shop: If using VR on primary trigger, please check R181 100k (0805 size SMD)resistor at LM1815 pin7. (min 47k, max 180k; 100k recommended: you can find 100k in rescue kit marked as 104 ).
- R181 is connected to LM1815pin7, so NOT the two pads right next to LM1815 pins 6 & 7 (which is the 3 pin header connected to LM1815 pin5, leave that 3 pins open!)
- You do not actually need the R181 resistor when using HALL as primary, but recommended to install it anyway to avoid future surprise (if using VR later). Anyway, have a note about this in the logs (or trigger related notes) that you write for your ECM.
- believe it or not, I independently copied the old R181 note (we even had an edit conflict when I saw your question and added more info on the pin).
- remove D100 if you use powerflyback GenBoard/Manual/PowerFlyback/RemoveD
- change C103 to 1nF if using secondary trigger HALL : Manual/InputTriggerHardWare/ReplaceC
- set AREF=256 BuildProcedures/SectionThree (not required but recommended)
Q: Are you supposed to replace a resistor on the board or change a value in the config for AREF=256? It's not really clear.
