Package Included:

1 pcs ESP32-CAM Module

1 pcs 160° OV2640 Camera

ESP-01s 1 MB WiFi Microcontroller ESP8266 ESP01s Replace ESP-01 ESP01

 

ESP-01s 1 MB WiFi Microcontroller ESP8266 ESP01s Replace ESP-01 ESP01 - Here comes ESP-01s, the new version of the well-known ESP-01.

ESP-01s vs ESP-01 differences:
1. Red power LED is removed (saving a couple mA and good for battery operated project)
2. Blue LED is now on pin 2
3. Has silkscreen with pin labeling on the back
4. Has far more chip capacitors for better working stability
5. The WiFi range has been slightly increased
6. Has a pull-up resistor connected between CH_PD and Vcc, so only need to connect Vcc & Gnd for booting and running

Specifications:
+ 32-bit RISC CPU: Tensilica Xtensa LX106 running at 80 MHz
+ 64 KiB of instruction RAM, 96 KiB of data RAM
+ 8 Mb (1 MB) External QSPI flash
+ IEEE 802.11 b/g/n Wi-Fi
+ Integrated TR switch, balun, LNA, power amplifier and matching network
+ WEP or WPA/WPA2 authentication, or open networks
+ SPI, I²C, I²S interfaces with DMA (sharing pins with GPIO)
+ UART on dedicated pins, plus a transmit-only UART can be enabled on GPIO2
+ 1 10-bit ADC

NodeMCU v2 Amica ESP8266 CP2102 4MB WiFi Microcontroller ESP-12E ESP12

NodeMCU v2 Amica ESP8266 CP2102 4MB WiFi Microcontroller ESP-12E ESP12 - This module is an ideal version, still using the yellow Tantalum Capacitor (vs the black color which is inferior) and more premium components. 
It will be more stable when used in the Lab or in the field. (See picture no.3)
It's not the CHEAPER NodeMCU v3 as it's bigger and uses the inferior USB Chip, the CH340.
Facts about v3:
1. Not a continuation of NodeMCU v2 and produced by a different manufacturer
2. Bigger size (58 x 31mm) than v2 (48 x 26mm)
3. Not breadboard-friendly, v3 will fill the entire breadboard pin, so it can't be used to connect other peripherals.
(See picture no.5)
