TinyS3[D] is the best of Unexpected Maker's super popular range of "Tiny" development boards.

It's packed with amazing features and peripherals, wireless connectivity and stacks of Flash and PSRAM, all in the same tiny package size as the original TinyPICO!

TinyS3[D] combines the previous TinyS3 and TinyS3 uFL boards into a single board, giving you more options and no need to pick one or the other. It also replaces the VBAT ADC sense pin with an I2C battery fuel gauge.

TinyS3[D] has full drop-in compatibility with the previous TinyS3 versions, but Unexpected Maker did need to extend the board length by 1.3mm to fit everything in and still allow for a solid, well-tuned RF layout.

The TinyS3[D] includes the following features:

  • Dual 32bit Xtensa LX7 cores @ up to 240Mhz
  • RISC-V Ultra Low Power Co-processor
  • 2.4GHz Wifi - 802.11b/g/n
  • Bluetooth LE 5 + Mesh
  • 8MB QSPI Flash
  • 8MB of extra QSPI PSRAM
  • 700mA 3.3V LDO Regulator
  • Low power RGB LED
  • ULTRA LOW Deep Sleep Current
  • USB-C Connector with back-feed protection
  • Native USB + USB Serial JTAG
  • LiPo Battery Charging
  • Pads on the back for JST PH connector
  • 5V Sense Pins
  • 17 GPIO
  • NEW 3D High Gain Antenna AND u.FL connector
  • NEW I2C Battery Fuel Gauge
  • Compatible with TinyPICO & TinyS2

NEW! Two antenna options on the one board!

TinyS3[D] includes an onboard antenna and a u.FL connector for an external antenna on the same board, and you can switch which antenna to use via the RF switch on the fly from inside your code!

The onboard antenna is selected by default, so you never need to worry about the RF switch being in a bad state, or the ESP32-S3 getting damaged if you forget to plug in an external antenna.
