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.

3 PRODUCT FEATURES
This section highlights notable features of the ESP-BoB Kit.
3.1 Compatibility
Due to the double row female header interface, the ESP-BoB is compatible with a range of products. 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.

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.
