Power options
The EV-COG-BLEINTP1Z board is powered up by means of the VDD supply from the MCU cog through the 32 pin connector (P1). The VDD
supply is shared between RF transceiver, BLE and WIFI via jumper P5. Shunts must be placed in appropriate positions as shown in the following
figure to power up different blocks.
P5 can also be used for measuring current flowing through different rails by
connecting an ammeter between VDD and VDD_RF/VDD_BLE/VDD_WIFI.
32 pin Hirose connector
The Hirose connector P1 interfaces the EV-COG-BLEINTP1Z board with the MCU Cog. The connector carries VDD, UART, SPI2 and GPIO
signals from MCU cog board. The pinout details are given in the following table

Bluetooth Low Energy Chipset
The EV-COG-BLEINTP1Z has a Bluetooth low energy chipset EM9304 from EM Microlectronic. The chipset contains BLE protocol stack along
with some profiles. The MCU cog communicates to EM9304 by means of SPI2. The user will need to send BLE configuration commands and data
over SPI. The following table captures the signals connected to EM9304
Component EM9304 pin number EM9304 pin name MCU cog signal
U1 4ENABLE GPIO27
15 GPIO0 SPI2_CS0
16 GPIO1 SPI2_CLK
17 GPIO2 SPI2_MISO
18 GPIO3 SPI2_MOSI
20 GPIO4 SPI2_RDY
The Jumpers P6 and P7 are provided to isolate SPI_CS and SPI_CLK lines
connected to BLE while working with RF transceiver daughter cards. But shunts must
be placed on these jumpers for BLE to work.
WIFI module connector
The connector P9 supports the WIFI module ESP8266. The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack.
The module communicates to MCU cog via UART TX and UART RX lines. Each ESP8266 module comes pre-programmed with an AT command
set firmware which allows easy programing over UART. For more information & support concerning the WiFi module please follow the links below:
