Both DAP V1 and V2 are doing good to me.
PSoC4 (and Cortex-M0+ based PSoC4+ ) have not a lot of protection methods supported.
The Ra-07h module comes in “OPEN” state. So debugging is possible over either generic ARM CMSIS-DAP or with Cypress proprietary KitProg2/3/4 probes.
HELTEC keeps no secret that debugging of their modules is possible with KitProg3. Thus, it is likely that the factory setting for the modules is “PROTECTED”.
Status of Ebyte E78 is currently unknown. If they ship the module with “KILL” setting - there is likely no way to connect and flash your own custom firmware into this module. However, if it comes in “PROTECTED” mode - there is a chance to re-use it by device acquisition with KitProg3 followed by “mass erase” instruction.
