Pin Mapping Differences Between the EZ-BLE™ PSoC® Evaluation Board (CYBLE-214015- EVAL) and the BLE Pioneer Kit (CY8CKIT-042-BLE) - KBA216236

Version: **

 

Question:

Are there differences between the pins exposed on J1 and J2 headers of the EZ-BLE PSoC Evaluation Board (CYBLE- 214015-EVAL) and the pins expected by the J10 and J11 headers on the BLE Pioneer Kit (CY8CKIT-042-BLE)

 

Answer:

Yes, there are differences in pin mapping between exposed pins of EZ-BLE PSoC Evaluation Board and BLE Pioneer Kit. The EZ-BLE PSoC Evaluation Board quick start guide explains how to use the board with the BLE Pioneer Kit and the differences in pin mapping. This is also explained below. 

Figure 1 shows the J10 and J11 headers on the BLE Pioneer Kit.

The EZ-BLE PSOC Evaluation Board can be plugged on to these headers as shown in Figure 2

The EZ-BLE PSoC Evaluation Board’s J2 and J1 are plugged in to J11 and J10 headers of BLE Pioneer Kit respectively. 

The EZ-BLE PSoC Module exposes a subset of the GPIOs that are expected on the BLE Pioneer Kit. Therefore, the evaluation board for the module has several pins that do not map to any port of the module. In addition, some pins exposed on the J1 and J2 headers of the evaluation board differ from the pins expected on the J10 and J11 headers of the BLE Pioneer Kit. A table showing the complete pin mapping and highlighting differences is shown below. The table specifies NC (No Connect) for the pins that are not available on the evaluation board.

*EZ-BLE PSoC Module shorts the digital and analog power rails of PSoC 4 BLE (highlighted rows in blue) 
**Pins differ from the pins expected on the BLE (highlighted rows in yellow)
***The EZ-BLE PSoC Module has the P4_0 pin however this is connected to the Cmod capacitor on the EZ-BLE PSoC Evaluation Board (and similarly P4_1 pin is connected to Ctank capacitor) and is not exposed on the J1 header.

Note: The EZ-BLE PSoC Module is supported on PSoC®CreatorTM 3.3 SP1and later versions. While the GPIOs available on the EZ-BLE PSoC Module and consequently on the EZ-BLE PSoC Evaluation Board are limited, every functionality available on a PSoC 4 BLE silicon is available on the EZ-BLE PSoC Module. The only exception is the CapSense® Gestures Component that handles one- and two-finger gestures. This Component is not available on the EZ-BLE PSoC Module.

Headers (on CYBLE-214015-EVAL): Usage description

                                                            
HeadersUsage description
J3   

It is used to short VDDD and VDDR.

    

Note: J3 can be ignoredfor usage if customers insert CYBLE-214015-EVAL into CY8CKIT-042-BLEsince VDDD and VDDR are short in CY8CKIT-042-BLE. However, if customers use the CYBLE-214015-EVAL separately, customer need to short J3 based on application requirement.

  
J5   

It is used to short VDDD and VDDA.

    

Note: J5 can be ignoredfor usage if customers insert CYBLE-214015-EVAL into CY8CKIT-042-BLEsince VDDD and VDDA are short in CY8CKIT-042-BLE. However, if customers use the CYBLE-214015-EVAL separately, customer need to short J5 based on application requirement.

  
J6   

It is used to short P3.5 of CYBLE-214015-01 module to either/both of P3.5 and P2.7 of CY8CKIT-042-BLE
