Schematics
Ballast resistors for W h/IR LEDs for ~1V over CAT4101
Bank selection and control LED filter
Power sanitization, RPI mapping, RPI accessory functions
Status LED control, buzzer, and level translation
Unused components
Maximum output current of 750mA cont. for UV leds. Currently set to ~680mA.
USB HID Keyboard Simlator
AVR status LEDs must have a VF > 1.8V
Use GST18E05-P1J Mean Well power supply
Status LED board
LED ESD protection required
as LED's are near board edge.
Protects LEDs and
microcontroller I/O.
On-board exposure LEDs
Use TE Connectivity 1483352-1 to connect status LED board
Changelog
1.10 Split UV leds to between CAT4101. Removes need for ballast resistors. Wh/IR leds unchanged.
UV LED current reduced. Added pullup resistor to allow RPI to identify hardware version.
1.10b Updated R74 to (correctly) be DNM.
Use one Littelfuse 60R075 per UV LED to add overheat protection to UV LEDs.
