Tanmatsu: hardware

WiFi, BLE and IEEE802.15.4 radio module

This ESP32-C6 based module provides the board with access to Wifi, BLE and IEEE802.15.4 (mesh network) connectivity while also controlling the LoRa radio module.

Camera connector

The camera connector is used to connect a CSI camera mdoule. It is pinout-compatible with the camera connector on the Raspberry Pi Zero and 5. Note that software support is limited to a subset of Raspberry Pi compatile camera module sensor chips such as OV5647.

QWIIC & Stemma QT compatible I2C & I3C connector

This connector can be used to connect external I2C or I3C based accessories. Both Adafruit and Sparkfun make a variety of modules and cables which could be connected to this port.

USB-C device port

This port is used to charge the battery, to program and debug the ESpP32-P4 and ESp32-C6 microcontrollers and to install apps and browse files from your computer.

USB-A host port

This port can be used to connect an USB device to the Tanmatsu.

SD card slot

Accepts micro SD memory cards including modern high speed SDIO 3.0 cards.

Battery connector

Allows for connecting a single cell Lithium Polymer or Lithium Ion battery cell. Using a protected cell is mandatory. Unprotected cells could potentially be drained below their lowest allowable voltage, which causes damage to the battery. Current control, over voltage protection and propper constant voltage/current charge control are is built-in into the Tanmatsu mainboard.

Sensor connector

Can be used to connect an I2C connected sensor PCB.
