Connector

Type

Description

K2

3-pin header

This jumper selects either the internal or external voltage supply. For the proper position

for the jumper, see Figure 2. It is also possible to measure the current drawn by the

sensor. For this feature, ensure all other electrical components on the sensor board are

physically removed.

PMOD

PMOD (Male)

This connector can be used to connect the ESCom to a Renesas MCU Development Kit

and communicate with the sensors connected via the K4 or the PMOD (socket)

Connector.

PMOD

PMOD (Female)

This connector can be used to connect a Renesas PMOD sensor to the ESCom board.

Check the Renesas website for information about the available PMOD devices.

K4

14-pin connector

Port for connecting the environmental sensor boards to the ESCom communication

board.

K5

2-pin header

Connector for an optional external power supply (see Figure 2).

D1

Power LED

LED illuminates blue if the communication board is powered correctly.

D2

Status LED
