Introduction

EV-COG-BLEINTP1Z board is a connectivity Cog board for MCU Cogs (EV-COG-AD3029LZ and EV-COG-AD4050LZ). This board enables wireless RF transceiver connectivity, Bluetooth Low Energy connectivity and WIFI connectivity for various IoT applications.

  • The following ADI wireless RF daughter boards are supported via SPI interface
  • BTLE - available on board and can be communicated via SPI interface
  • WIFI - provision to support ESP8266 via UART (not available in the kit)

This user guide describes the connector pin out, power options and jumper settings available on board.




Hardware details

Board image

Primary-side

Secondary-side

The board consists of

  • 32 pin Hirose connector (P1)
  • Power header (P5)
  • Wireless RF transceiver connector (P2, P3, P4)
  • Bluetooth Low Energy Chipset
  • WIFI module connector (P9)
  • Debug header/test points

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

Wireless RF transceiver connectors

The wireless RF transceiver connectors consist of three connectors P1, P2 and P3, which support ADF7023, ADF7024, ADF7030, ADF7030-1 and ADF7242 RF transceiver daughter boards. 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

15GPIO0SPI2_CS0
16GPIO1SPI2_CLK
17GPIO2SPI2_MISO
18GPIO3SPI2_MOSI
20GPIO4SPI2_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:

The following figure shows the orientation of the module. Pinout details of the module connector are given below.
