E18-MS1PA2, E18-MS1PA2-IPX, E18-2G4Z27SI or E18-TBH-27 USB Test Board are new boards from Ebyte with the CC2530 chip. The manufacturer promises better technical parameters but hides the real name of PA (power amplifier) even if you remove the cover shield from the board.
The existing documentation from the manufacturer instructs to compile a firmware with the HAL_PA_LNA flag. The same flag is used with the old and well-known CC2591 PA. But the board uses different pins to control PA and LNA. Therefore the standard firmware for CC2530+CC2591 chips does not work.
The configurable firmware allows you to avoid this problem. It can create the necessary firmware for you. You should use the following settings to prepare a router firmware for that board. Of course, you may other features to the firmware like a status LED indicator.

Can i use not PWM ports for TXEN / RXEN?
I need 4 hardware PWM out….
Owner
Hi. TXEN and RXEN depend on a power amplifier. PWM also uses a fixed pin number. It is possible; you may find a variant where TXEN/RXEN and PWM may co-exist.
Sandr
Based on your info? HW PWM can be set on next pins^
PWM #1 pins: P13 or P16
PWM #2 pins: P10 or P20
PWM #3 pins: P14 or P17
PWM #4 pins: P11 or P23
And what you can reccomend configuration?
What about:
PWM #1 pin: P13
PWM #2 pin: P20
PWM #3 pin: P14
PWM #4 pin: P23
TXEN pin: P11
RXEN pin: p10

Thanks for the quick response, I correctly understood that pins 11 and 10 cannot be used.
Owner
If a power amplifier on your board uses these pins, you cannot use these pins for other purposes.
Alexey
Hello. Sorry in advance for my English (I am Russian speaking).
Question about RFS 2401 control, for the maximum signal, should I send a logical unit to pins 11 and 10? or there is nothing to do, everything will work well?
Owner
Hello. The firmware sets the maximum power signal programmatically. Pins are used to enabling the power amplifier.
