Also down on that page for nice!nano v1 "Regulator: AP2112K (code G3P, up to 600 mA, leaks 55uA), you can replace it with XC6220 (up to 1A, leaks 8uA)" so the voltage regulator leaks less than half of this cheap board. however if you power LED from it it draws much more anyway and if you need much less then the VDD pad could work (or GPIO pins).
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
It is marked in red on that wiki page https://github.com/joric/nrfmicro/wiki/Alternatives
