1. Evaluation Kit Introduciton
In this section, we'll introduce the function and usage of each EVK, and diagram attached at the end of
each paragraph.
1.1 EVK of BX2400-dRF0xp-S1c
This EVK is applicable to all BlueX BLE chips except RF01. Items (1) to (18) will be introduced as
below.
(1) USB Type C Connector
A. USB 5V power input.
B. It provides USB to convert to UART, and links to UART(P12/ P13) connector on module.
(2) Primary Power Switch
Please compare with #9, secondary power switch. Status listed as below:
#2 Switch #9 Switch EVK Power Module Voltage
Up Up 2ea AA batteries 3.0V
Down Up 2ea AA batteries 3.0V
Up Down DC 5V from #3 4.2V
Down Down DC 5V from USB 4.2V
According to operating voltage ranging from 2.3V to 3.6V, please be noticed it can only be
using 2ea AA batteries when BX2416 module on EVK.
(3) D5V External Power Connector
A. External power input port, DC 5V.
(4) RF0x Module Power Connector
A. Module power output connector, available for outputting power for external circuit.
B. When EVK using USB power or D5V, here it outputs 4.2V.
C. When EVK using 2ea AA batteries, here it outputs from batteries.
(5) IO Expanding Connector
A. RF0x Module IO and power expanding connector.
