Missing wifi module?


Just received the LimeNET-Micro from crowd supply and I’m excited! However, it’s missing the SMA for the wifi and the wifi module itself is not populated. Is that normal? It is version v2.1 according to the print on the PCB. I have looked around for an update mentioning that being gone, but I haven’t seen anything. Is this expected? Can I get one with wifi still?


Hi @paulsorensen5,

WiFi module is not populated, there is provision for it only. You still can purchase it separately:

Soldering is quite simple.


Soldering of module is enough,
or some configuration in resistors must be changed too?

Is there a way to still purchase the board with the wifi module? The crowd supply order page didn’t make it clear that it wouldn’t be populated.

This has never been offered on sale, would be a special build and I’d have to check the MOQ and lead time.

Oh okay, that’s disappointing. I suggest somebody update the https://wiki.myriadrf.org/LimeNET-Micro_v2.1_hardware_description page and remove “SDIO Wi-Fi module” from the “LimeNET-Micro board features:” section. Or at least note that it isn’t populated. Thank you for your answer!

Some were built for network operator customers with WiFi module and cellular duplexers fitted, hence why the wiki notes these other configurations. However, the specs as stated on the Crowd Supply page are the ones you should look at when purchasing. Will look at updating the wiki to make this clearer.

Hello @9a4db,

Sorry for late response!

To add Wi-Fi module to LimeNet-Micro v2.1 you have to solder these components (check pictures for more information):

  1. IC30 (Wi-Fi module WF111-A) Digikey PN: 1446-1031-6-ND
  2. R146, R147 (1k 0402 resistor) Digikey PN: RMCF0402FT1K00TR-ND
  3. R144 (49.9R 0402 resistor) Digikey PN: 1276-3469-6-ND
  4. C218, C220, C221, C222, C223 (100nF, 16V 0402 ceramic capacitor) Digikey PN: 81-GRM155R71C104KA88
  5. C224 (22uF, 10V 0603 ceramic capacitor) Digikey PN: 810-C1608X5R1A226M
  6. J20 (SMA connector) Digikey PN: CON-SMA-EDGE-S-ND

SMA connector is optional because Wi-Fi module WF111-A has internal ceramic antenna. Only WiFi module WF111-E will work with external antenna.

Thank You Zack no rush,
considering this option to have more flexibility on my
lime togo box :wink:
