ESP-BoB Kit 1 DESCRIPTION The ESP-BoB Kit is an unassembled kit designed to interface with ESP development boards, and other similarly sized boards. BoB stands for “Breakout Board”, which is exactly what this product does. The central double row female headers can accept many of the common microcontrollers, up to 20 rows in length and between 8 to 10 rows spacings in width (20.32 mm, 22.86 mm, 25.40 mm). The breakouts on both sides include a footprint for a row of female header, a row of male header, and a row of screw terminals.

The board can interface any product up to 20 pins in length at standard 2.54 mm/0.1 in pitch and with three different widths. The widths are: - 8 Pin spacing = 20.32 mm 9 Pin spacing = 22.86 mm 10 Pin spacing = 25.40 mm The physical dimensions of the ESP-BoB are shown Figure 4. As an example, Figure 1 shows a commonly used ESP32 development board plugged into the ESP-BoB. This particular ESP32 development board has a row spacing of 19 pins, and a width of 10 pins (= 25.4 mm). Since the breakout of the ESP-BoB is generic, all the pins are simply numbered and not assigned. This is done because many different ESP32 development boards have a different pin assignment. Figure 1: Example application. 3.2 Features of the ESP-BoB The features of the ESP-BoB are graphically shown in Figure 2. All the pins are broken out on either side with a footprint for a row of male header pins, a row of female header pins, as well as a row of screw terminals. Additionally, there are two pinouts available for the ground planes (top and bottom combined) of the board. There are four mounting holes. Figure 2: Features of the ESP-BoB. 3.3 Mark of Authenticity Authentic PTSolns PCBs have a black solder mask color and are marked with the “PTSolns” logo in white silkscreen printing. The “Canadian Designed” symbol, consisting of the Canadian Maple Leaf with the word “Designed” underneath, can also be found on the PCB in white silkscreen printing. The “PTSolns” trademark and the “Canadian Designed” symbols are shown in Figure 3.
