Description

STAMP-PICO features an ultra-compact design with two low-power Xtensa® 32-bit LX6 microprocessors at 240MHz on a PCB as tiny and delicate as a postage stamp. low power consumption. It is ideal for any space-constrained or battery-powered devices such as wearables, medical devices, sensors, and other IoT devices.

  • 1, MULTIFORM: 5 options of installation, means endless possibilities! (SMT, DIP, fly wire, grove interface), with a high-temperature resistant plastic shell, 3D antenna and components can be better protected.

  • 2, LOW-CODE DEVELOPMENT: STAMP-PICO supports UIFlow graphical programming platform, scripting-free, cloud push; and fully compatible with Arduino, MicroPython, ESP32-IDF, and other mainstream development platforms to quickly build various applications.

  • 3, HIGH INTEGRATION: STAMP-PICO contains 5V->3.3V DC/DC port, GPIOx12, programmable RGB light x1, button x1, finely tuned RF circuit, providing stable and reliable wireless communication.

  • 4, STRONG EXPANDABILITY: Easy access to M5Stack's hardware and software ecology system: a wealth of sensors, actuators, functional modules, and accessories to choose from, Extremely fast adaptation.

ESP32 Downloader

Before burning, you need to connect a USB-TTL burning board for STAMP-PICO, and proceed according to the board silkscreen connect. Install the driver corresponding to the burning board on the PC.

The most convenient way is to Purchase the STAMP-PICO package version with downloader , the line sequence of the matching downloader It is consistent with STAMP-PICO, it can be directly plugged in for programming without wiring. Currently M5 provides downloaders of two driver chip versions, CP210X (applicable to CP2104 version)/CP34X (applicable to CH9102 version) driver compressed package. After decompressing the compressed package, select the installation corresponding to the number of operating systems Package to install. (If you are not sure which USB chip your device uses, you can install two drivers at the same time)
Driver name Applicable driver chip Download link
CP210x_VCP_Windows CP2104 Download
