The ES24TX is a 250mW ExpressLRS micro module that fits most radios available in the market (TX16, FrSKY X9D+ / X7 etc...) 
While the Pro version can output up to 1 Watt, the reality is 250mW is still more than enough for long range while consuming less power and generating less heat, which removes the requirement for a fan.
Note that this version does not come pre-assembled.
