There is no board file with correct pins but it is easy to make one, can you find out pinout or schematics? Or do you know the pinout of your board is compatible with Nordic nrf52840 dongle? More details here https://infocenter.nordicsemi.com/topic/ug_nrf52840_dongle/UG/nrf52840_Dongle/hw_description.html?cp=4_0_5_5
There is topic about Espruino for nordic 52840 dongle, you may try builds from posts below this one http://forum.espruino.com/conversations/323658/?offset=100
Anyway, it is just about correct board file, no changes are needed in Espruino source.
