USB 2.0 and Micro-B offer an IP67-rated waterproof option that withstands post-solder reflow while minimizing water ingression. Many consumer and industrial applications experience wet conditions that could cause failure in connectors. With 3.0A/5.0A current to enable faster and safer charging, Molex offers a wide range of USB Type-C Connectors that are physically robust and electrically reliable. The mating tongue design protects the interconnects from possible damage caused by mishandling, shipment or assembly processes. Molex’s USB Type-C I/O connectors use high-temperature plastic as housing material and a 3-tier insert-molding process to help ensure high mating durability. Most of our USB products are TID certified and comply with various dimensions to help prevent costly electrical damage. The high voltage is not problematic, but the low voltage can be if there are too many inputs connected to one output.Some USB connectors don’t comply with the required USB specifications, which can cause costly electrical damage. Note: The GPIO outputs have 100 Ω series resistors the GPIO inputs have 1K pullup resistors to 3.3V and the input threshold on the 541 chips is 2V high and. The following calculations explain this limitation: The 3.3V output is polyfuse-protected and can source up to 500mA. If one BrightSign player is driving the inputs on another BrightSign player, then you can drive at most three inputs from one output. The connector can also supply 3.3V at up to 500mA to an external device. Connect the other side of the switch to one of the ground pins on the DB15 connector.

Connect one side of the switch to the switch input.The connector also allows the connecting of external contact closures to the ground. If you want to connect another device, then the output is capable of sourcing or sinking up to 3.3V at 24mA, but there is a series resistor of 100Ω in each line.

Connect the LED outputs to the LED ANODE.

This connector is used to allow the BrightSign to control external LEDs or other devices requiring 24mA of current or less. The Switch/LED connector is a DA15 Female. The following table and diagram illustrate the pinout of the DA15 GPIO connector on earlier models: The following table describes the outputs (numbered left to right) on the 12-pin GPIO for Series 4 (XTx44, XDx34, HDx24) and Series 3 (XTx43, XDx33, HDx23) players:
