EX-CSB1 FAQ¶
CH340 USB Drivers¶
Windows USB driver is required.
CH340 driver info https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers
Note that only one program can use the USB connection simultaneously. Close the device monitor or other programs when uploading.
Track voltage¶
DCC is a square wave signal. The voltage of the track power supply will be present on each rail 50% of the time. Use the DC scale to measure voltage -- each rail vs GND should be 50% of track power supply.
Few digital multimeters will provide a consistent/useful reading on the AC scale.
OLED¶
Select 132x64 or 128x64
If one results in blank screen or image is shifted, try the other.
Some CSB1 may have had screen display customized to display track status.
myTrackStatus.example.h
Power supply¶
If your power supply is less than 5A, add a line in config.h to set overcurrent reporting lower - 90% of track power supply.

EX8874 on CSB1¶
EX8874 on CSB1 requires no modifications to the EX8874 solder pads.
A second identical power supply or Y-cable will be needed for the EX88874 track power.
Startup - Tracks / Power¶
Add lines to myAutomation.h to define track modes and power state at startup.
Note that the power command is placed after the change in track mode.

Fault reporting¶
Continuous faults will be reported with power on, if track power supply is not connected.
An initial fault report at power-on is not an issue.
Overcurrent reporting¶
Some - 600mA or less - overcurrent reporting on the programming track is not unusual. This is due to lack of precision of the ESP32-WROOM ADC, and the 250mA trip current for the programming track when not reading/writing CVs.
There is a command <C PROGBOOST> to override the 250mA limit. Do not use it unless you are comfortable that your loco/decoder does not have issues (which 250mA is designed to protect).
Note that <C PROGBOOST> remains in effect until the EX-CommandStation is restarted.
WiFi¶
WiFi configuration is different, starting with version 5.7.0.
config.h is used for WiFi configuration in earlier versions.
Link to 5.7.0 WiFi Configuration
Note that if the new WiFi configuration commands are sent via a WiFi connection, your existing connection will drop. Current connection info should be reported on the OLED.
