Salut
Din ce am citit, noul IR Receiver nu este crucial pentru servomotor. Este pentru a suporta mai bine mai multe consumatoare legate deodata (mai multe motoare).

Citez:
"The new 9398 4x4 Crawler is released with a new version of the RC Receiver (6020086), which got a "V2" label printed.
The newest RC Receiver was upgraded with a CMOS motor driver giving less power loss.
This upgrade with a new CMOS motor driver is not directly connected with the release of the new LPF L-motor, but LEGO has been looking for this opportunity for a while and now the right driver is available.
The timing is however connected with the launch of the 9398 4x4 Crawler, and the new RC Receiver enables two PF L-motors to be connected to the same output on the RC Receiver. This is not possible with the earlier RC Receiver versions released! (4506085, 4566756)
RC Receiver was first modified in 2009, when support to 'access to extra address space' was implemented and a minor fix related with a 'single pin mode' design flaw. By that time the LPF RC Protocol was also updated and new documentation was released (version 1.10).
This documentation was later found to be incorrect and a new document with the protocol description was then released in 2010 (version 1.20).
The current hardware change to the RC Receiver is released with no further modifications to the LPF RC Protocol.
The new receiver got a "V2" label just because the first upgrade in 2009, was purely a firmware change.
So we have now the following list of LPF RC Receivers released:
Element ID 4506085 - Original hardware, with RC Protocol firmware version 1.00 (released in 2007).
Element ID 4566756 - Original hardware, with RC Protocol firmware version 1.20 (released in 2010).
Distinguishes by: LED double blink on startup.
4566735 is the element ID for the corresponding set (8884-1) sold separately.
Element ID 6020086 - Second hardware, with RC Protocol firmware version 1.20 (released in 2012).
Hardware modifications: New CMOS motor driver with lower power loss.
Distinguishes by: LED also blinks twice on startup and "V2" printed label on the front."
