Best way to get 16MB WROOM modules?

A project that I've been working on needs to go production. Unfortunately, I can't seem to find any 16Mb (128Mbit) WROOM-32 or WROOM-32D modules in quantity. I'm in the USA but I don't mind a global supplier as long as they're reliable. I need FCC approval so no grey suppliers on Aliexpress, unfortunately. Does anyone know anywhere to find them? I'd be interested in 1-4 reels (650-2600pcs). I already sent a request to sales at www.espressif.com but I figured I'd ask here to see if anyone knew a source where I potentially could avoid lead times.

thanks in advance!

To be clear: I'm looking for ESP32-WROOM-32 or ESP32-WROOM-32D with 16MB / 128Mbit Flash AND the PCB antenna, NOT the antenna connector.

https://www.espressif.com/sites/default ... ion_en.pdf

According to that document, there is no MPN but it is identified as "ESP32-WROOM-32D (16 MB)"

Those are only 4MB but it is cool they have 24k in stock.

Try grid connect?

Analog Lamb didn't have ability to deliver quantity and the CE/FCC doesn't look convincing.

alb32-wrover doesn't have any certificate, plus GPIOs 16&17 are not connected (used for SPI-RAM) and that could be a problem if the board is designed for ESP32-WROOM and uses those pins.

Hats off to Espressif sales for following up promptly and accurately. If anyone needs quantity of modules, they're an email away.
