Hello,
I asked the price for the minimum 5 pieces thus € 10 for PCB and 9 € for shipping by HK post, delivered in 16 days after the order.
The Cam86 can be powered with 7.5V minimum; for Peltier I took it as voltage regulator:
Ultra-small-size-DC-DC-step-down-power-supply-module-3A-adjustable
Cam will be powered by 9V and 5V Peltier; there is makes -30 ° C under ambient temperature, that is enough well for me.
