RAWX_Logger_Switches

A switch PCB for the ZED-F9P_FeatherWing and ZED-F9P_FeatherWing_USB

Contains:

Three slide switches:

• ON/OFF power control (pulls the EN line low to disable the 3.3V regulators on the FeatherWing and the Adalogger)
• Base/Rover mode (pulls A0 low for Base mode, leaves it floating for Rover mode)
• Survey_In mode (pulls A3 low to enable Survey_In (RTCM) mode when in Base mode)

Two push button switches:

• EVENT (pulls A2 (ZED-F9P EXTINT) pin low to create a TIM_TM2 event message)
• STOP (pulls A1 low to stop logging and close the log file)

NeoPixel:

• Indicates the status of the Logger

Based extensively on the Adafruit Feather(Wing) product range

The Eagle files are available in the Eagle folder

BOM

• The ON/OFF, BASE/ROVER and SURVEY_IN slide switches are: E-Switch part EG1218 (Farnell / Element14 part 2787232)
• The EVENT and STOP push switches are: e.g. Multicomp MCDTS6-1N 160gf (Farnell / Element14 part 9471685)
• LED1 is a Sparkfun / Worldsemi WS2812B NeoPixel (Mouser part 474-COM-13667)
• LED2 is an 0805 (2.0x1.25mm) red LED: e.g. Wurth Electronik 150080RS75000 (Farnell / Element14 part 2322077)
• R1 is a generic 0805 or 0603 1K resistor: e.g. Multicomp MCWR06X1001FTL (Farnell / Element14 part 2447272)
• C1 and C2 are generic 0603 0.1uF (100nF) ceramic capacitors: e.g. Murata GRM188R71H104JA93D (Farnell / Element14 part 2688523)

LED2 and R1 are optional if you are using the NeoPixel
