What type of IPEX connector is typically used on LoRa modules? I thought generic “IPEX” would be specific enough, but my antenna supplier needs a IPEX connector model spec. ---

That’s entirely down to the device, there is nothing about antenna hardware connectors that is ‘typical’ for LoRa modules. Does your device not have a data sheet? Can you send your antenna supplier a picture? ---

> [@descartes](#): > > Can you send your antenna supplier a picture That won’t work without including a rules for reference as the dimensional changes are very small. I recently had to acquire some male connectors for a board and the options on Ali were that confusing/similar that I ordered some of a couple of different types. [This message](https://www.thethingsnetwork.org/forum/t/lds01-with-external-antenna/39083/14) clearly states which version the LDS01 has, from looking at it I hadn’t noticed it was different to the ones I (up till recently) considered ‘standard’. ---

@descartes The module datasheet only mentions “IPEX”. I contacted the module maker, but no response yet. Checking the iPEX web site ([https://www.i-pex.com/](https://www.i-pex.com/)) shows several RF connector models that -at first glance- look alike, but apparently not compatible. I found a connector picture with inscription “13 IPX”. This would be IPEX connector model **MHF I**. So now I answered my own question 😉 Hope this is useful for anyone looking for the same info. ![IPX13](https://www.thethingsnetwork.org/forum/uploads/default/original/3X/d/9/d95d3edd01116cda599f2a644b813173d30dad3c.png) ---

Yup, how much quicker would it be for us to see the entire module or even mention the part number right from the beginning. But as I have all of the RAK modules on hand and some on my desk from last weeks output: > [@The WORKBENCH part 5](https://www.thethingsnetwork.org/forum/t/the-workbench-part-5/31726/57): > > TinyThing4200 = ProMini with RAK4200 to off-load the LoRaWAN element, leaving plenty of space for sensors and extended firmware but still accessible for those that don’t code ARM all day every day.[TinyThing4200\_RAK] [TinyThing4200\_ProMin] > [@The WORKBENCH part 5](https://www.thethingsnetwork.org/forum/t/the-workbench-part-5/31726/58): > > MiniPrototyping4200 = ProMini, RAK4200 and a surfeit of connectors. Pile of these about to go out with a variety of sensors to do some getting started training via remote. [MiniPrototyping4200] There will be a TTIG in the box for their local gateway. I can confirm these are industry standard u.FL connectors. ---

@kersing @descartes Thanks for your help. The same type of connector is used on different modules: Globalsat LM-130, RAK4600, RAK4200 (phased out), RAK4270 ---

Plus the RAK4260, RAK4631, the entire range of MCU + RFM95 boards I do and about a zillion other radio based modules.
