Role: Electrical Engineering
I joined the Square Stand team to layout several PCBs for performance improvements, mechanical fit, and production testing, but my responsibilities grew to include engineering validation as well as international production support. Before the launch of the Square Stand, I performed electrical signal integrity validation for various PCBs and cables in the product to ensure reliable communication amongst the iPad, main microcontroller, and connected peripherals. To ensure the product’s ability to operate in different environments, I set up several system cycling tests using an environmental chamber.
Designed to replace the traditional cash register, the Square Stand is Square’s second hardware product. It is designed to be used in conjunction with Square’s Register app run on an iPad. It comes shipped with a custom USB hub, which allows the connection of peripherals such as bar code scanners and receipt printers.
