1. OUTLINE STAMP-PICO is the smallest ESP32 system board launched by M5Stack. It focuses on cost-effectiveness and simplification. It embeds an ESP32-PICO-D4 IoT control on a small and exquisite PCB board as small as a stamp (STAMP). core. With the support of ESP32, this development board integrates 2.4GHz Wi-Fi and Bluetooth dual-mode solutions. Provide 12 IO expansion pins and a programmable RGB LED, combined with ESP32 internal interface resources (UART, I2C, SPI, etc.

3. QUICK START STAMP-PICO adopts the most streamlined circuit design, so it does not include a program download circuit. When users use it, they can download the program through a USB-TTL burner. The wiring method is shown in the figure below. 3.1. ARDUINO IDE Visit Arduino's official website(https://www.arduino.cc/en/Main/Software),Select the installation package for your own operating system to download. >1.Open up Arduino IDE, navigate to `File`->`Peferences`->`Settings` >2.
3.2. BLUETOOTH SERIAL Open the Arduino IDE and open the example program `File`->`Examples`->`BluetoothSerial`->`SerialToSerialBT`. Connect the device to the computer and select the corresponding port to burn. After completion, the device will automatically run Bluetooth, and the device name is `ESP32test`. At this time, use the Bluetooth serial port sending tool on the PC to realize the transparent transmission of Bluetooth serial data. #include "BluetoothSerial.
#if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED) #error Bluetooth is not enabled! Please run `make menuconfig` to and en able it #endif BluetoothSerial SerialBT; void setup() { Serial.begin(115200); SerialBT.begin("ESP32test"); //Bluetooth device name Serial.println("The device started, now you can pair it with bluetoot h!"); } void loop() { if (Serial.available()) { SerialBT.write(Serial.read()); } if (SerialBT.available()) { Serial.write(SerialBT.read()); } delay(20); } 3.3.
#include "WiFi.h" void setup() { Serial.begin(115200); // Set WiFi to station mode and disconnect from an AP if it was pre viously connected WiFi.mode(WIFI_STA); WiFi.disconnect(); delay(100); Serial.println("Setup done"); } void loop() { Serial.println("scan start"); // WiFi.scanNetworks will return the number of networks found int n = WiFi.scanNetworks(); Serial.println("scan done"); if (n == 0) { Serial.
} else { Serial.print(n); Serial.println(" networks found"); for (int i = 0; i < n; ++i) { // Print SSID and RSSI for each network found Serial.print(i + 1); Serial.print(": "); Serial.print(WiFi.SSID(i)); Serial.print(" ("); Serial.print(WiFi.RSSI(i)); Serial.print(")"); Serial.println((WiFi.encryptionType(i) == WIFI_AUTH_OPEN)?" ":"*"); delay(10); } } Serial.
