Description
Common feature of EPI. EP2 Receiver :
Type: ISM
SX1280IMLTRT RF Module
MCU: ESP8285
Frequency Range: 2400 to 2500
Receive refresh rate: 25 - 500
Working voltage: 5V
Dimension: 10mm*10mm*6mm
Bind procedure:
1.Supply power to the EP1/EP2 rx, wait until the LED on the RX is off, immediately turn off the power, and then repeat again the above steps. When the RX is powered on for the third time, the LED light will start to double-flash, which means that the RX enters the binding mode
2.Insert the ES24TX module or other DIY 2-4G ELRS TX to Radio transmitter, and choose External RF mode to CRSF protocol, then you can find ELRS menu from the Radio systems(Need to copy the ELRS.LUA file to the SD-Card tools first), Enter into ELRS and press [Bind], the LED on the RX module will getting to be solid if bind successfully.
3.Receiver LED status meanings:
EP1/EP2 RX: LED solid means bind successful or Connection established; LED double-flash means in bind mode; LED flash slowly means no signal connection from the TX module; LED flash fast means in WIFI hotspot mode, you can connect the WIFI of the RX and upgrade firmware of the RX via visit 10.0.0.1(password:expresslrs)
Flying freestyle like you stole it

I like the rxs for the size how small they are and how light they are cuz I use them on micros tp3s toothpicks drones. I plan on adding over to other things maybe planes power parachutes and such

Checked wiring 3 or 4 times before powering up and it instantly went up in smoke, never had a receiver do this before. Checked the board with an ohm meter and sure enough power was shorted to ground somewhere on the circuit board. Super bummed about this purchase

These elrs receivers are great, small, simple, powerful. In the process of switching out a bunch of old frsky stuff.

Ep2 wouldn’t flash newest Elrs but this ep1 did and it gets better range, I know the slim ceramic antenna may draw you but if you want to really get out there this is the one.

Just recently switched to ExpressLRS and don't a compelling reason to use any other link system, even Crossfire, given that ELRS supports 900Mhz as well. These recievers support flashing over wifi, which, for me has been seamless. I've been flying these for a few weeks and no failsafes yet (knock on wood). The one issue I seem to have is that after initially binding the TX & RX (which I did using a passcode set when flashing firmware, so they just bind automatically when I turn them on - TX first, then RX) the link works perfectly, but after leaving the RX unpowered for some time (let's say 30minutes) then powering back on, the reciever does not immediately go into binding more (led flashing) but what looks like bootloader more (led solid) and never binds. Power cycling does not resolve this issue, but if I leave it on for some time (let's say 5-10min) it eventually drops out of bootloader mode and binds. Then if I power cycle again, it binds normally. Then if I leave it unpowered again for ~30min I get the problem again. Eventually, after a few days of this, the reciever stops having this issue and binds normally when powered and the issue never comes up again. I've had this happen on 3 seperate EP1 RX's. I checked if I accidentally soldered to or shorted the bootloader mode pad, but I definitely did not - certainly not on all 3 reciever. I'm not sure if this issue is due to a hardware or firmware flaw, or maybe I flashed it with some inopportune settings, but upon examination, it does not seem to be the case. This is the reason for my 4-stars vs. 5. Otherwise, ELRS is king and happymodel recievers are an excellent choice.

The pads are pretty small. Other than that I set my TX output to 100mw @ 500hz and it is silky smooth and never fail safes. I recommend the ES24TX module no fan needed unless u want to use 250mw output. Though 100mw tests out to 20 miles lol
