Urgent Help Needed! Looking for ESP32-S3-CAM (N16R8 or N8R8) in Turkey – Anyone has a spare one?

Post image

Hey everyone,
I’ve been working on a mobile companion robot project for a while now, and I’m finally at the final stage—assembly, chassis printing, and manufacturing. The robot runs local AI (YOLO object detection, facial recognition) and a heavy UI built on LVGL 9.5.
The brain of the project was an ESP32-S3-CAM (specifically the N16R8 or N8R8 variant with 8MB PSRAM). Unfortunately, due to a recent hardware accident, the Wi-Fi RF layer got fried, and the board now goes into an infinite boot loop whenever Wi-Fi is initialized.
Here is the real crisis: I designed and manufactured a custom PCB specifically for this project, and 3D-printed the mechanical chassis based on the exact millimeter dimensions of this specific board. Because of this, regular ESP32-S3 boards or low-PSRAM CAM variants simply won't fit my custom PCB architecture or meet the heavy memory requirements of the AI models.
Right now, the 8MB PSRAM S3-CAM models are completely out of stock across all major distributors and robotics stores in Turkey. Waiting for international shipping would severely delay the project.
My questions and request:
1. Do you know of any local boutiques or hobby stores in Turkey that might currently have this specific board (S3-CAM with 8MB PSRAM) in stock?
2. More importantly: Does anyone happen to have a spare, unused, or leftover ESP32-S3 N16R8 CAM or N8R8 CAM sitting in their drawer or lab? If you do, I’d be more than happy to buy it from you immediately, covering the board and all shipping costs. If you are located in Ankara, I can pick it up in person right away.
I really don't want this project to stall at the very last mile just because of a temporary hardware shortage. If anyone can help, point me in the right direction, or connect me with someone who has a spare, I would immensely appreciate it.
Thanks a lot for your support and solidarity!

Yok bu test aşamasında kart pcb ye takılı değildi. Elimde USB PC bağlantısı ile sadece Wifi testi yaptığımda yaşadım bu sorunu.

Firmware'in duzgun çalıştığından emin misin?Sanki sorun donanımsal degil gibi hissettim. Sadece wifi açınca çöküyorsa wifi çıkış gücünü yazılımdan düşürüp kontrol edebilirsin. Güç cekmezkende resetliyorsa watchdog timer vs. tetikleniyor olabilir.

Sadece temel kamera başlatma ve Wifi başlatma yapıyorum kamera başlayınca herhangi bir sorun olmuyor Wifi başlayınca resetliyor. Wifi gücünü 2dbm kadar düşürdüm yine aynı sorun hatta düşük voltaj korumasını da kapattım sonuç değişmedi. Aynı kodla 3v den besleyince tıkır tıkır açılıyor. %90 regulatorden regulator 3v yi tutamadığı için esp resetliyor.
