This item is an ATMEGA328 microcontroller (328-PU or 328P-PU as available) in 28-pin DIP package. This is the type of chip used in my ARPIE kit, and is offered for sale to enable a simple self-upgrade path for ARPIE owners who do not own programmer hardware or are not comfortable using it.
The chip is programmed with the ARPIE 6 firmware, which was released in September 2019 and supports the CV TAB. Please see the ARPIE product page for more information. It also has an Arduino Duemilanove bootloader programmed on it and can be further updated using a suitable USB-TLL programmer.
The upgrade is compatible with any of the ARPIE kits I have previously sold on Tindie. It can also be used to replace a lost or damaged chip or build a DIY ARPIE from scratch.
When replacing the chip, be careful not to bend the legs and make sure you fit the chip the correct way around. Take basic anti-static precautions (e.g. touch a grounded metal surface prior to handling the chip). With reasonable care, anyone can change the chip.

|Shipping Rate||Tracked||Ships From||First Item||Additional Items|
If you are placing an order from outside the UK you must agree to allow up to 6 weeks for delivery from the shipping date. While most items arrive quickly, customs delays are quite common.
If an item has not arrived after this time we can offer a refund or a replacement product provided that you let us know within 10 weeks from dispatch. If a replacement is preferred and the original shipping was untracked, we will ask you for the additional postage costs to upgrade shipping of the replacement by a tracked service.
It is your responsibility to handle any extra steps needed to receive your product (such as collecting an undelivered item from your local post office / booking a redelivery / paying customs duty) within appropriate time windows. If an undamaged item is returned to us due to a missed delivery/failure to pay customs etc. we can re-send it to you (at your expense) or we can process a refund of original order value, less shipping cost.
We will try to mark packages with any special instructions you provide with your order. However, we will not be responsible for problems resulting from our failure to do so, from the instructions not being followed correctly by the delivery courier, or for safety of packages left in ‘safe place’ etc.
