# 0.5.3
|
|
|
|
Traces clean-up to reduce chances of botched fabrication
|

|
https://github.com/rusefi/hw_microRusEfi/issues/165 progress miniUSB option
|
|
https://github.com/rusefi/hw_microRusEfi/issues/180 improvement for SD+BT wiring (SPI Flash pinout was changed to accomodate but no one uses SPI Flash anyway)
|

https://github.com/rusefi/hw_microRusEfi/issues/184 BOM issue wrong size of 2.7K resistors
|
|
|
|
# 0.5.1
|
|
TBD, in the works!
|
|
Added J19 the optional USB bulk head connector.
|
|
|
|
Some passives are now 0402 in order to move stuff from the back side of the board.
|
|
|
|
Analog input RC filter changed from 10nF to 100nF.

|
U9&U10 are now controlled directly without TLE8888, those are now useable
|
|
|
|
# 0.5
|
|
May 2020
|
|
Four more low-side channels.
|
|
Many more changes! See https://github.com/rusefi/hw_microRusEfi/pull/155
|
|
|
|
R21,R33,R80,R81 DNP, R122,R123,R124,R125 100R: U32,U33 are driving smart coils via PD4, PD3, PD2, PD1
|
|
R21,R33,R80,R81 0R, R122,R123,R124,R125 DNP: TLE8888 is driving external smart coils instead of U32,U33 via PD12, PD13, PD14, PD15. U32,U33 not used.
|
|
|
|
R2 0R - TLE8888 watchdog reset will reset stm32 reset and vice versa, stm32 reset would reset tle8888
|
|
|
|
Four more high-current low-side drivers on board! (but we do not have firmware to run U9&U10 via TLE8888 at the moment)
|
|
|
|
U9 uses AV6 & AV10 pins.
|
|
|
|
U10 uses AV8 and AV9 pins.
|
|
|
|
It's now possible to power up microRusEFI with 5v with the case closed - please feed your USB +5v into pin #19 AV4.
|
|
This would affect AV4 reading while USB cable is connected so plan accordingly.
|
|
|
|
We are now using stm32f427 chip instead of stm32f407. As of May 14, 2020 we simply use the same stm32f407 firmware on the stm32f427 chip.
