Description

Describe the Bug

Since the supported hardware information of the pixelspace capsule65i does not provide any information about the MCU (an APM32F072CBT6) in the README-file, the target file format for compiling action is set to hex instead of the desired bin-format. (At least, thats what I think has happend. Also I'm not shure, if I report this "bug" correctly, sorry for that.) - Best regards :)

Research direction
The issue is that the QMK Configurator compiles to .hex instead of .bin for the pixelspace/capsule65i keyboard. To fix, locate the keyboard's directory under `qmk firmware/keyboards/pixelspace/capsule65i/`. Check the `rules.mk` or `info.json` file for the MCU definition (likely missing or incorrect). The MCU is an APM32F072CBT6, which probably requires a .bin format. Update the configuration to set the appropriate output format, possibly by setting `BOOTLOADER` or `FORMAT` variables. Refer to the QMK documentation on how to specify the output file format.
