This is a placeholder for a 1602 LCD display with controller to be used in your design. I took measurements from the display at https://www.banggood.com/3Pcs-IIC-I2C-1602-Blue-Backlight-LCD-Display-Module-For-Arduino-p-983482.html?p=TH241428726122015109 (affiliate link). Note that this display includes in I2C controller. If you need a placeholder for just the display disregard the smaller PCB below.
