Unable to find Breadboard schematic for Omega2sp

[Chandan Rajashekhar]

Hi,
Omega 2sp can boot without Dev kit? If yes please let me know how can i boot/access.
I have tried by passing 3.3v and ground and tried to scan wifi ssid unfortunately not shown any ssid.
I have found below solution for Omega2 but its not working Omega2SP, please assist on this?

Thanks in advance.

Just buy a ams1117 3.3 just check that it work to 3.3v because you can find different values, if you want to configure your wifi just execute wifisetup con console

Omega2S Documentation & Resources
Omega2S Datasheet

For a very minimal HW config:
connect

• the GND pins (pin 1, 22, 23, 25, 63) to the power supply's GND
• the 3.3V pins and the VDD_FLASH pin (pin 8, 9 and 32) to the power supply's 3.3V
• an External antenna directly to the u.FL connector on the module
  OR
  a ceramic chip or a PCB trace antenna to pin 24 (WIFI_RF)

It's a very good idea to connect a USB-to-Serial module to UART0 to get a Serial Console and you could watch what's going on
( - for example - during boot).
Connect module_TX to UART_RXD0 (pin 40), module_RX to UART_TXD0 (pin 39), module GND to GND.

Good luck!

@György-Farkas , Thank you very much for your response and suggestion, I have tried by shorting all GND pins and VCC pins separately and connected to USB to TTL connector (https://hub360.com.ng/product/usb-to-ttl-converter/).
Unfortunately it didn't worked, Onion Omega2SP not showing in my wifi scan list.
Also i tried module_TX and RX connecting to same USB to TTL converter (Drivers not supporting), suggest me if any supported drivers available.

Tried on Windows, Linux and Mac

To Power on Onion Omega2SP is it required to short any pins? or once we connected VCC and GND it will power on automatically?

@Chandan-Rajashekhar First of all you must use an appropriate 3.3V, minimum 500mA (0.5A) power supply.
Some power supply with 800..1000mA (0.8..1A) output current capability would be better.

Your YP-01 PL2303 (???) USB to TTL converter module is only a USB-to-Serial converter and can't provide enough current for an Omega2.

You will find the WiFi AP of your Omega2S+ if it can fully boot. Presently your Omega2 is not working at all.
