 +Instead on an STM32F103, this dongle uses a [[http://www.cksic.com/en/|CKS]] {{ :jtag:ic_mcu_cks_cks32f103xb.pdf|CS32F103}} (sometimes CKS32F103)  ({{ :jtag:ic_mcu_cks_cks32f103xb_en.pdf|datasheet translated to english}}).
 +I've seen pin compatible alternatives (ST STM8S003 vs Nuvoton N76E003), even architecture compatible (ST STM32F103 vs GigeDevice GD32F103), but they always had some differences (architecture, electrical pin properties, registers, ...).
 +The CS32F103 seems like a complete clone of the STM32F103 (exact same pinout, architecture, registers).
 +So far I could not not see any difference (I tested flash, USB, SWD).
 +I guess this micro-controller is so popular that it was just a question of time until it was ripped-off.
 +To check if this is a complete clone you could decapsulate the chip and compare the silicon die, or check the errata behaviour (I can't imagine they re-implemented it themselves, up to the mistakes).
 +The next step would be to have a CS32F103 chip in a package marked as STM32F103.
