Yes, in addition to that there is also:<p>* RFduino - has the advantage of being available on RS. Downsides: 16 kB version, no 32 kHz crystal, very few IO pins exposed.<p>* BMD-200 - 32 kB version, cheap if you&#x27;re in the US, well made, 15 GPIOs exposed, no 32 kHz crystal<p>* Simblee (by same guys as RFduino) - 32 kB version, 32 kHz crystal, more GPIOs, <i>tiny</i>, quite expensive though<p>Nordic maintains a list of modules:<p><a href="https:&#x2F;&#x2F;www.nordicsemi.com&#x2F;Products&#x2F;3rd-Party-Bluetooth-Smart-Modules" rel="nofollow">https:&#x2F;&#x2F;www.nordicsemi.com&#x2F;Products&#x2F;3rd-Party-Bluetooth-Smar...</a>
