Model selection and protocol selection (ELRS version)
The TX12MKII comes with a CC2500 single-chip multi-protocol internal RF module, which is compatible
with several different protocols. To view the latest list of all compatible protocols, please visit https://www.-
multi-module.org/ Please note that new protocols will be constantly updated and added to the latest
firmware. Some new protocols may require firmware upgrades.
TX12MkII ELRS units are equipped with an internal ELRS module, capable of providing 10mW-250mW
RF output. In non-extreme circumstances, 100mW output at 250Hz update rate is recommended, as
higher RF output and update rates may significantly reduce battery life and generate excessive heat.
