I know the price of Leaf Maple in Seeedstudio is about 45$, not included Li-ion Battery. MapleTree is 39$ with about 3000mA Li-ion Battery, better than Leaf Maple.

Leaf Maple VS MapleTree

1.Leaf Maple uses USB Mini, MapleTree uses Micro USB which is more convenient. Most of smartphones use micro USB,not mini USB.
2.Leaf Maple uses BQ24010 as battery charger IC, MapleTree uses BQ24075T. BQ24075 is with Power path function.It is as same as smart phone battey charger system.
3.Leaf Maple uses LDO, MapleTree uses Buck DC-DC with 600mA output. It’s more efficiency.
4.MapleTree is a mobile device with about 3000mA Li-ion Battery. You can use smart phone PSU to charge and power it, same as smart phone.
5.We will provide more pin compatible boards for MapleTree, for example, LCD, Dot Matrix LED, Sensors, Basic IO board and so on.
6.MapleTree has a switch that can disable DC-DC.It also is for mobile.
7.MapleTree provides a interface for SWD and USART1, with our Lamblink tool, It’s more convenient for engineers and fans. LambLink = STLink V2+USB to USART + USB Hub.

Welcome to try our MapleTree.

The original Maple boards are no longer in production, Leaflabs stopped making them several years ago and has been shutting down their Maple related websites for the past year.

Only clones of the boards are now available, with these 2 being probably the closest clones

As far as I’m aware both Baite and ITead are Chinese companies.

I know Olimex also does a Maple type board, but its a lot different to the Maple

Hi

I think your product is similar to the Microduino, except your board is a bit bigger and has headers

https://www.microduino.cc/store

We added support for the Microduino ARM board about a year ago, as I think one forum member has a Microduino ARM board

I think its a shame that everyone makes clones of the original Maple R1 and not the Maple RET6, as the STM32F103RET is a much better MCU as it has DAC etc, and it is the same size as the F103RB, so it would be easy for companies to make a much better board, at only $1 cost

How much will be priced your F405RG ?
Which on-board peripherals will be available ?
(I just want to compare it with Arch_Max with ETH and SDCard, priced at $19.95)

This is our Maple RET6 Version. Except MCU, other parts are as same as MapleTree.

peripherals will be in extended board like Arduino.

That seems like a lot of money for a board that has no software support or ethernet connectors.

Once you creep into the $20 range you are competing with raspberry pi and its clones.

With the ArchMax they constantly keep dropping the price to under $20, so I wonder if they get any sales at all at $39

STM have loads of boards in the $20 price range as well.

This whole sector is incredibly price sensitive, with the majority of people on the board moving to the STM32 platform as you can buy the BluePill for under $2 including postage
