CY8CKIT-042-BLE-A user switch connections

[alkhc_3773311]

Hello everyone,

Could someone please confirm whether or not there are pull-up resistors within the module for this kit. I'm specifically interested in the connections for the User Button(connected to pin p2.7). From the schematic of the module and the board itself there doesn't seem to be any external resistors.  However, while using the PSOC creator software, the schematic for the User Button displays a pull-up resistor. Is this pull-up resistor-contained within the module ?

Kind regards,

Alisha Khan

Dear Alisha-san,

It's a PSoC Device internal pull-up resistor.

According to the PSoC 4: 4200_BLE Famil Datasheet Table 8. GPIO DC Specifications

SID69 Rpullup Pull-up resistor Min 3.5k Typ 5.6k Max 8.5k
