The project team is keen on getting to know the the crystal frequency stability/tolerance. Any information is much appreciated.
Best regards,

Hi Matias,below is the electrical characteristics of the crystal .

@akif-durmaz Hi ，what i mean is you can try to use another ethernet connector.

Hi，Omega2S+ need to add an extend wifi antenna.you can use ipex connector to connect an extend wifi antenn or use the ANT PIN to connect a pcb wifi antenn.

@Malcon4 here is the ethernet port that Omega2 using .

@akif-durmaz
Hi, i had checked the Normal ethernet connector（RJ45），it seems that the inside schematic isn't as the same as yours. Here the connector's sch has the same channel coil of RX/TX.SPEC of HR913550A

@akif-durmaz Hi ,please add a screenshot of the ethernet connector and transformer 's schematic.

The lastest Omega2S reference schematic had deleted the R401~R406，C403 and C404.

@akif-durmaz Hi ,For the Omega2S reference schematic ,there are two options for the ethernet connection,option1 is using ethernet transformer ,option2 is a simpler circuit which using resistor and capacitor to instead the transformer . and each of the option can work.
I had checked your ethernet port circuitry screenshot, there are some connection is not right, you can't connect the omega2S's ethernet signal line to the ethernet port.

And if you complete the Omega2S firmware and you need to update the customized-firmware, maybe you can reference below two ways:

1. Manual Firmware Installation,using the CMD :
   sysupgrade <FIRMWARE FILE NAME>
   You can use the USB Port or Micro-SD to copy the firmware to Omega2S.
   
   Reference the operation: https://docs.onion.io/omega2-docs/manual-firmware-installation.html#
   2)Firmware Flashing With Web Recovery Mode
   
   
   Reference the operation: https://docs.onion.io/omega2-docs/Firmware-Flashing-Web-Recovery.html

Hi Matias，if you want to know the partition of the Omega2S ,you can use the cmd :
cat proc/mtd
to check the detail.

Hi, I‘m onion Jeff. usually, our specifications will give some guidelines for reflow soldering， and about your manufacturing guidance, as it based on you product，it is hard for us to issue guidance.

1. About the wash cycle , .
   Our module is the same with the wifi module or BT module on the market. you just need to be careful that the silk screen on the label is erased by the no-clean flux .
2. Is there a recommended stencil thickness?
   Our module Spec had the module's thickness parameter
   
3. Tape and Reel are 56mm wide.
   Sorry for the mistake, the real of the actual tape and reel is 44mm, we will change it soon and update the packaging parameter.

Hi，1. you can add a pull-up resistor to the Omega2S HW_RST pin and add a pull-down resistor to the SW_RST pin. 2.the current supply of VCC need at least 500mA.

Hi,it seems that the schematic is ok. You can check that if the SMT issue or you can check the SDCD PIN Voltage when the sd card insert .

Hi, if you don't need to use Micro SD Card .

1. As Onion Firmware's SD Card funtion will be actived when SD_CD PIN at High-level.When you keep using Onion Firmware,you can use pulldown resistor to set the SD_CD PIN to low-level.
2. You can set each SD Card PIN to GPIO Mode.

Hi，Omega2S+ need to add an extend wifi antenna.you can use ipex connector to connect an extend wifi antenn or use the ANT PIN to connect a pcb wifi antenn.
