The Taida Century nRF52 mini board / nRF52832 Gold Core development board is available from several online retailers and is similarly priced to the SparkFun nRF52832 Breakout, or a smaller (and cheaper) alternative of the Nordic nRF52 DK.
This board is supported by Sandeep Mistry's nRF5 core, through the following variant Taida_Century_nRF52_minidev variant.h.
The development board itself is a nRF52832 breakout module, smd soldered to a generic development board. The development board was designed for the CC2640, and appears to be compatable with select breakout modules containing the following chipsets : CC2640, nRF52832, nRF51822.
According to the schematics below the generic development board is a CC2640RSM/RGZ Module Test Board V1.0 from rf-smart.taobao.com.
