ESP32-CAM NodeMCU 5V WiFi ontwikkelbord met OV2640-cameramodule

La placa ESP32-CAM requereix una alimentació estable de 5 V DC, i es recomana un corrent mínim de 500 mA per evitar reinicis quan la càmera està activa. El rang de tolerància del pin 5V sol ser entre 4,75 V i 5,25 V. Alimentacions fora d’aquest rang poden causar fallades o danys permanents.

El mòdul suporta UART (velocitats típiques fins a 115200 bauds), SPI (fins a 40 MHz, depèn del cablejat), I2C (fins a 400 kHz com a master) i Wi-Fi 802.11 b/g/n (velocitat màxima teòrica de 72,2 Mbps, limitada per l’entorn i el firmware). El bluetooth BLE suporta connexions de fins a 2 Mbps en condicions òptimes. La càrrega d’imatges via Wi-Fi depèn de la mida del fitxer i de la qualitat de l’enllaç.

L’ESP32-CAM està dissenyat per funcionar entre -20 °C i 85 °C. No té dissipador integrat, de manera que en operacions prolongades, especialment gravant vídeo o amb la Wi-Fi activa constantment, pot escalfar-se per sobre de 65 °C en ambients calorosos. Es recomana una ventilació adequada. Si s’utilitza en caixes tancades, s’aconsella monitorar la temperatura del microcontrolador.

El mòdul ESP32-CAM mesura aproximadament 40 mm x 27 mm x 4.5 mm, i el seu pes és d’uns 7 g. El contingut de la caixa inclou el mòdul ESP32-CAM muntat amb la seva càmera OV2640 preinstal·lada. No s’hi inclouen cables, targeta microSD ni adaptador de programació USB-Serial.

The ESP32-CAM board requires a stable 5 V DC supply, with a minimum current of 500 mA recommended to prevent resets when the camera is active. The tolerance range for the 5V pin is usually between 4.75 V and 5.25 V. Supplies outside this range may cause faults or permanent damage.

The module supports UART (typical speeds up to 115200 baud), SPI (up to 40 MHz, depending on the wiring), I2C (up to 400 kHz as master) and Wi-Fi 802.11 b/g/n (theoretical maximum speed of 72.2 Mbps, limited by the environment and firmware). BLE Bluetooth supports connections up to 2 Mbps under optimal conditions. Image upload via Wi-Fi depends on file size and link quality.

The ESP32-CAM is designed to operate between -20 °C and 85 °C. It does not have an integrated heatsink, so during prolonged operation, especially when recording video or with Wi-Fi constantly active, it may heat up above 65 °C in hot environments. Adequate ventilation is recommended. If used in enclosed cases, monitoring the microcontroller temperature is advised.

The ESP32-CAM module measures approximately 40 mm x 27 mm x 4.5 mm and weighs about 7 g. The box contents include the assembled ESP32-CAM module with its OV2640 camera pre-installed. Cables, microSD card and USB-Serial programming adapter are not included.
