Customer:
I am developing a V1 hardware prototype based on an ESP32 microcontroller with a MEMS I2S microphone. My aim is to avoid hand-soldering sensitive components and instead use fully assembled, tested boards from a single supplier where possible.
I would like to ask:
• Do you currently supply an ESP32 development board suitable for prototyping?
• Do you supply a fully soldered MEMS microphone breakout (I2S, 3.3 V)?
• Have these components been tested together, or can you recommend a compatible pairing?
• Can both boards be connected and used without custom soldering (headers, jumper wires, etc.)?
For now, I am looking to purchase 1–2 units for V1 testing. If the V1 prototype is successful, I would then like to explore the possibility of small-batch manufacturing (approximately 25-50 units) with a single supplier.

I would appreciate your advice on what you currently offer and what you would recommend for this approach.
Thank you for your time.

Razvijam V1 hardverski prototip temeljen na ESP32 mikrokontroleru s MEMS I2S mikrofonom.
Cilj mi je izbjeći ručno lemljenje osjetljivih komponenti te, ako je moguće, koristiti potpuno sastavljene i testirane pločice od jednog dobavljača.
Zanima me sljedeće:
• Nudite li trenutno ESP32 razvojnu pločicu pogodnu za prototipiranje?
• Nudite li potpuno zalemljenu MEMS mikrofon pločicu (I2S, 3.3 V)?
• Jesu li ove komponente testirane zajedno, ili možete preporučiti kompatibilnu kombinaciju?
• Mogu li se obje pločice koristiti bez dodatnog lemljenja (pinovi, jumper žice, breadboard itd.)?
U ovoj fazi tražim 1–2 komada za V1 testiranje.
Ako V1 prototip bude uspješan, u sljedećem koraku bih želio razmotriti malu serijsku proizvodnju (otprilike 25-50 komada) s jednim dobavljačem.
Bio bih zahvalan na vašem savjetu o tome što trenutno nudite i što biste preporučili za ovakav pristup.
Hvala unaprijed.
