Some time ago I received a Wio terminal from Seeed and I remember thinking “great, finally a decent colour display system, cased, with decent IO capability – but why didn’t they put a battery in it?”. Well, now they have – or rather they have brought out a plug-in battery pack (650maH Lithium) – not only that but it has a status LED, four Grove analog/digital ports, a Grove I2C port and a Grove UART port built in – all in an ABS enclosure like that of the Terminal itself.
Finally the battery pack (underside of the 3-photo set at the top of this blog entry) has a USB-C input connector for charging though I note it doesn’t seem to do fast-charge, just normal 5v USB charging. You can however use the supply with the WIO terminal while it is charging, so perhaps that’s no big loss.
The Wio Terminal product already has two multi-function Grove connectors and that too uses USB-C for power (not needed when the battery pack is in use). While I’m here, the Wio terminal has a lovely colour display, 5-way control switch, combined power/reset switch, three user-programmable buttons and a micro-SD card slot.
At this point I’ll send interested users over to the Seeed site for more specs on both products and details of the significant range of Grove boards and their 10-way Grove shield for the Raspberry Pi Pico which also just arrived.
Elsewhere I’ve written about the RPi Pico and the Grove Shield product.
Of interest, the whole lot came well packaged – how long and at what postal cost – well, that depends where you live.
My only question now is – what do you DO with a product like this.. unlike the M5Stck products it is not based on ESP32 so you can’t easily put Tasmota on it.
The Seeed Wio Terminal includes a Cortex-M4 microcontroller, motion sensors, an LCD display, and Grove connectors to easily connect external sensors. It is tempting to compare this to the M5Stack Core2 (which CAN be Tasmotised, is more expensive but also contains a battery). Of course you can hook up the Seeed Studio product to the Arduino development environment but it’s all down to finding examples including display use.
