@@ -8,10 +8,33 @@ deRFmega128 is a family of modules produced by Dresden Elektronik.
 deRFmega128 modules are based on [ATmega128rfa1](http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-8266-MCU_Wireless-ATmega128RFA1_Datasheet.pdf),
 MCUs. It include 16MHz main and 32K RTC crystalls and (depending on module type) integrated or not integrated 2.4GHz antenna.
 
-These modules are available in three variants: [deRFmega128-22M00](https://www.dresden-elektronik.de/produkt/24-ghz-avr-derfmega128-22m00.html) with integrated antenna,
-[deRFmega128-22M10](https://www.dresden-elektronik.de/produkt/24-ghz-avr-derfmega128-22m10.html), and [deRFmega128-22M12](https://www.dresden-elektronik.de/produkt/24-ghz-avr-derfmega128-22m12.html) without integrated antenna.
