Question:

What are the differences between the pins exposed on J1 and J2 headers of the EZ-BLE PSoC Evaluation Board (CYBLE-224110-EVAL) and the pins expected by the J10 and J11 headers on the BLE Pioneer Kit (CY8CKIT-042-BLE)?

Answer:

Yes, there are differences between the pins exposed. 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.

Figure 3 shows the pinout and details of the EZ-BLE PSoC Evaluation Board (CYBLE-224110-EVAL), which is a fan-out board for the EZ-BLE PSoC Module (CYBLE-224110-00).

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 4.0 and 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-224110-EVAL): Usage description

Headers	Usage description
J3	It is used to short VDDD and VDDR. Note: J3 can be ignored for usage if customers insert CYBLE-224110-EVAL into CY8CKIT-042-BLE since VDDD and VDDR are short in CY8CKIT-042-BLE. However, if customers use the CYBLE-224110-EVAL separately, customer need to short J3 based on application requirement.
